Gold mining company in Mexico and investing in gold advantages: Return rates of physical gold are never profitable if you invest in the gold jewellery. The reason being that the price of jewellery is not only determined by the gold rates but it also includes the making charges and this is the just the half story i.e. when you purchase the gold. Now, when you sell the gold, the story is totally different, the making charges are not considered and you get the money only for the pure gold based on the gold rates of that particular day. Take for example; the gold rate in Mumbai during December 2015 was 27000 Indian rupees for ten grams of 24 karat gold and assuming that you bought a gold necklace of 20 grams for about 60,000 Indian rupees which include the making charges too. Now, due to some reason you want to sell it and you go to a shop who quotes the price only for the gold that necklace contains and not for the stones it has or the copper which weighs it down to only 13grams and the cost of 13 grams of pure gold in 2020 is only 40000 Indian rupees in 2020, obviously, it is a loss deal for you and thus, poor return rates are one of the downsides to keep in mind while investing in physical gold.

Toiyabe contains at least two strongly mineralized fault zones with strong gold values on surface and in drilling. This evidence demonstrates the potential for gold-mineralizing fluids to travel from a deeper source through reactive, lower plate, carbonate rocks to the shallow mineralization encountered to date at Toiyabe. Several deeper drill holes have encountered low to moderate gold mineralization erratically distributed through comparable stratigraphy in nearby producing mines. Although the necessary structural complexities and traps required to host a large economic gold occurrence have yet to be encountered, a recent re-interpretation of stratigraphy and structure by Paul D. Noland indicates that this environment likely exists within the Toiyabe project boundary and may be responsible for at least some of the mineralization encountered within less favorable, upper plate lithologies.

The San Martin project is located 50 km east of the City of Querétaro in Querétaro State, and about 250km northwest of Mexico City. The city of Queretaro boasts a population of over 1 million people and is one of the safest states in Mexico. Major companies such as Bombardier Aerospace, Safran, Eurocopter, and Canada’s Héroux-Dvetek all have operations in Queretaro. In 1982, the area of San Martin was declared a National Reserve; however, by 1986, Luismin (previous owner) had reached an agreement to conduct exploration/exploitation in the area. Mining began in 1993 at 300 tpd and the production increased on a yearly basis to the present rate of 747 tpd with the capacity of 900 tpd. Find more info on starcore.com.

Looking to buy the best split wire loom? Here are some advices and extra details helping you to make the best choice. The liquid tight flexible non-metallic conduit (LNFC) is really a reliable option for a wide range of applications. It is built to be really hard-wearing and protective having the ability to give defense against water and flames. Plus, certain LNFC may be manufactured with multiple layers to provide extra strength. This is basically the most practical form of Plastic Flexible Conduit Fittings to make use of in locations which might be seen as potentially hazardous.

Rigid polyvinyl chloride (PVC) is similar to plastic plumbing pipe and is installed with plastic fittings that are glued in place. It can be bent after being heated in a portable heater box. Because the conduit tubing and fittings are glued together, the conduit assemblies can be watertight, making PVC suitable for direct burial in the ground for many applications. It is also allowed in corrosive environments.

Electrical metallic tubing, or EMT, is the most common type of conduit for exposed interior installations, such as in a basement or an unfinished garage or workshop. It is the lightest and thinnest of the rigid metal conduit types and comes in a few different diameters; 1/2-inch is the most standard size for household circuits. EMT is also called “thin-wall” and is relatively easy to bend with a tool called a conduit bender. EMT is permitted by the National Electrical Code (NEC) for dry and wet locations but requires special watertight fittings and connectors in wet locations. With proper installation, EMT raceway can serve as a circuit ground path and be used in place of a separate ground wire running inside the conduit. See extra info at Split wire loom tubing.

Do not attempt to work on your electrical wiring, switches, or outlets unless you are properly trained and equipped to do so. Electrical components in a building can easily cause an electrical shock, burn, or even death. Even when a hot line switch is off, one terminal on the switch is still connected to the power source. Before doing any work on the switch, the power source must be turned off by set­ting a circuit breaker to OFF or removing a fuse.

Flexible conduit protect wire and cables in the wire loom of construction or machine industry. They can also be used in household and auto, to make us more easy to move and manage wires. They are a series sizes of flexible conduit. General, flexible conduit vary size from 1/4? on up, and each conduit sizes have total different outer diameter and inner diameter. Today, we’ll share some quick guide to flexible conduit size. It is easier to choose an available flexible conduit sizes if you know the basic knowledge. Read extra info on https://www.flexconduit.com/.

If you’re going to protect a series of cables. I think split plastic flexible conduit is a good choice for you. Split plastic flexible conduit is split. It is easy for you to put cable in and take them out. Sometimes people will be worried about the cables will fall out from conduit. Please don’t worry about, after put all cables in, we will often use wrap tape to fix conduit. Most people know corrugated plastic flexible conduit and split plastic flexible conduit. But they know little about HDPE spiral flexible conduit. HDPE spiral flexible conduit is spiral conduit, makes it stronger and durabler than general flexible conduit. Furthermore, it can be produced in big diameter. We can produce 300mm outer diameter of HDPE spiral flexible conduit. It is nearly impossible for general flexible conduit.

Bump test gas cylinder online shop UK: Tests have shown that the relatively narrow cross section of the pure argon shielded weld has a higher potential for gas entrapment and, consequently, can contain more porosity. The higher heat and broader penetration pattern of the helium/argon mixtures will generally help to minimize gas entrapment and lower porosity levels in the completed weld. For a given arc length, the addition of helium to pure argon will increase the arc voltage by 2 or 3 volts. With the GMAW process, the maximum effect of the broader penetration shape is reached at around 75% helium and 25% argon. The broader penetration shape and lower porosity levels from these gas mixtures are particularly useful when welding double-sided groove welds in heavy plate. The ability of the weld bead profile to provide a wider target during back chipping can help to reduce the possibility of incomplete joint penetration that can be associated with this type of welded joint.

If you have been in the industry for any length of time, you will know the most common examples. This includes the likes of argon, helium, or carbon dioxide. Each gas offers its own unique properties when welding, and a case could be made for any of them. Carbon dioxide, for example, is low cost. It also makes for inferior welds, letting too much oxygen in. Argon, on the other hand, might be the perfect replacement.

WSD (weldingsuppliesdirect.co.uk) supplies a wide range of shielding gases specifically designed to optimise performance in particular conditions. In vehicle repair and manufacturing, argon-based gas mixtures are commonly used to MIG weld carbon and low alloy steels. Argoshield Light is one of those choices. It’s ideal if you are welding thinner carbon steel ranging from 0.6 to 5mm in thickness. The addition of oxygen to Argoshield increases arc stability to minimise spatter and fast weld speeds with its low heat input reduce distortion. So it’s perfect for our earlier example where the components of a car are being painted or powder coated after welding. Read extra info on Span Gas Bottle.

The primary task of a shielding gas is to protect the weld pool from the influence of the atmosphere, i.e. from oxidation and nitrogen absorption, and to stabilize the electric arc. The choice of shielding gas can also influence the characteristics of the weld penetration profile. The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. However, small additions of oxygen (O2) or carbon dioxide (CO2) are usually needed to stabilize the arc, improve the fluidity and improve the quality of the weld deposit. For stainless steels there are also gases available containing small amounts of hydrogen (H2). There are no rental charges on the cylinders. A large range of Calibration Gas regulator(s) are available from stock. Carry cases to compliment the cylinders are also available. The cylinders are non-refillable.

The risk of over-exposure to nitrous gases is considered to be low for oxy-fuel gas cutting, unless the work conditions are unfavourable e.g. hand held cutting in a confined space with a high duty-cycle. Plasma cutting with air or nitrogen generates higher levels of nitrous gases than oxy-fuel gas cutting and there is considerable risk of over-exposure. Free-burning flames generate the highest concentrations of NO and NO2, and the risk of over-exposure is also highest. Caution should be exercised during activities such as flame heating, flame straightening, flame brazing, flame spraying, etc – particularly as emissions from these processes are difficult to control. The flame should be extinguished when not in use. Source: www.weldingsuppliesdirect.co.uk.

Mag Drill HSS Cutter reviews: The first thing you should keep an eye on is the overall power output of a particular model. The key here is to make sure it delivers enough power to allow you to tackle and handle heavy-duty projects. In case you’re looking for something that you’re going to use occasionally, the power doesn’t play a major role but is still relevant. Most modern models use electricity as a source of power, but there are also some battery-powered models available on the market. As you can assume, cordless units come with certain limitations, especially when it comes down to battery life. In fact, the most important component of a cordless model is its battery. Therefore, if you’re planning on investing in a portable cordless unit, make sure it comes with a high-quality battery or else you’re going to experience a lot of downtime and underwhelming performance.

This is a perfect tool for on-site drilling. It looks very small but it is very powerful that a punch power of 22 pounds. It is very durable and efficient for all metal constructions. The spindle coolant equipped in it helps in keeping it from overheating during work time. The handles make it easy to shift it from left to right. The cooling lubrication for this one is gravity-fed. The hand wheel position can also be changed when you are working in a confined environment. It comes with a three-year warranty meaning the manufacturers assures of quality service from this tool. On the other hand, if you are not happy with this item, you can return it and get your full money refund. Therefore, consider buying it with confidence.

One of the things that most people struggle with when it comes to these tools is the overall weight. In simpler terms, mag drills tend to weigh significantly more than any other type due to the number of built-in mechanisms. If the weight isn’t a problem for you, then it might be the price. Even though these machines can be considered affordable, they definitely aren’t cheap. See extra details at Mag Drills.

Evolution Power tools magnetic drill press is one of the top-rated magnetic drill machines. It is most famous for its lightweight and compactness, excellent and well-constructed magnetic drill machine at a reasonable price. This is ideal for bridges, I-beams, and framework. This can provide 1300 Kgf. Or 2860 lbs f magnetic adhesion. Its maximum core diameter is about 28 mm or 1-1/8 inch. It can give a depth cut maximum of 50 mm or 2 inches. Evolution Power tools magnetic drill press also provide Weldon shank cutter fitting type -19 mm. It also offers a wide variety of tools to be used with Evolution Power tools magnetic drill press. This package includes a wide range of annular cutter, step drills and mini cutters, evolution cutting fluid.

Although this is a regular drill press and not a magnetic drill press, you can also use this one for steel drilling. The motor has a rating of ½ HP and in order to change the drill speed for metal drilling, you have to change the belt and pulley combination setting to the slowest speed. As a drill press, the RIKON 30-120 does not have the best performance. The feeding wheel is not well made and is awkwardly situated. Your chances of getting the back of your fingers caught between the feeding wheel and the belt tensioner are quite high and it is very painful. The packaging of this drill press is poor as well. If you are looking for a tool that you can use for drilling steel exclusively, we recommend that you stick to magnetic drill presses. Regular drill presses can work great for wood, plastics, and steel, but they don’t have magnets and is impossible to use for vertical and overhead applications.

Browse the best made in China industrial manufacturers catalog? China is one of the most rapidly growing countries in the world, and when it comes to manufacturing, China reigns supreme as the largest supplier in the world. According to statistics, 6 out of the 10 major export ports in the world are located in China. Much of China’s manufacturing is located in 5 major Chinese metroplexes.

The mining is among the major industries in the Chinese economy. The industry annually injects billions of dollars into the country’s GDP. China is the by far the largest producer of gold in the world, with the country producing about 463.7 tons of gold in 2016 (in comparison, the second biggest producer, Australia, managed to produce 274 tons in 2016). While South Africa, which had been the world’s top gold producing country for 101 years, has had its gold production declining by as much as 50% in the past ten years, China’s gold production has been increasing in recent years and has doubled in the past decade. Most of China’s gold deposits are found in the eastern part of the country, in the Liaoning, Henan, Fujian and Shandong provinces. Most of the gold produced in China is consumed locally as China is the world’s fourth largest gold consumer. The local gold consumption in China is equivalent to 9.2% of the global gold consumption. Coal mining is another important sector in China’s mining industry.

MIG welders tips: how to become a better welder and how to pick the best welding equipment. Make sure everything is ‘squeaky’ clean. TIG welding is not tolerant of any contaminants. Be sure to clean your base metal with a good degreaser, BEFORE you scrub it with a dedicated wire brush. Do not use the same brush on different kinds of metal. Wipe the filler rod down with degreaser, too. Get comfortable. Whenever possible, I like to be seated when I’m welding. Even in situations where sitting isn’t possible, any little adjustments to my stance or body position that make me more comfortable will have a noticeable effect on the weld.

Look for ways to create more efficiencies in the welding process. This includes examining such things as wire diameter, wire feed speed, voltage, travel speed, gas type, transfer mode, etc. For instance, if the shop is currently welding with a short arc process and a 75/25 blend of shielding gas, it may be more effective to switch to a different gas and a spray mode of transfer. Or, a change in process may be warranted based on the condition of the part. If there is oxide on the part, it may be easier to change to a process that will overcome contamination problems rather than try to clean each part before welding. Your welding supplier should be up to date on the latest technology and be able to advise you on new processes, machinery and consumables that can optimize welding at the shop. In some cases, it may be better to double bevel a joint to prepare it for welding rather than single bevel it. It is recommended to double bevel any material that is more than 3/4″ in thickness. Just this simple change in procedure can save quite a bit in weld metal. On a 3/4″ thick piece, a double bevel will use 1.45 lbs. per foot of weld metal while a single bevel will use 1.95 lbs. per foot.

Some tips on welding equipment, MIG and TIG welders, plasma cutters. Welders with a higher power output can work with thicker metals, but higher voltage welders will require special power supply set ups-either generators or appropriate power outlets. A welder with lower voltage in the 100’s will not be able to handle heavy duty jobs, but it can be plugged in and operated from any outlet. Any welder with power over 200 cannot run off a typical power outlet and will naturally cost more to run. In addition, welders will either run an alternating current (AC) that reverses itself at regular intervals or a direct current (DC) that flows in one direction and does not reverse itself. DC offers a steady rate of energy that leads to hotter temperatures and deeper weld penetration. AC welders usually cost less than DC welders, but the available electrodes are far more limited for AC. In fact, DC welders are more costly but remain popular because their higher power offers a wider selection of electrodes and a number of working advantages such as: simple arc striking, better penetration, and improved control. Welders who expect to work on a wide variety of projects may want to consider an AC/DC combination welder.

Flat-Position Welding Increases Welding Speed : It’s common knowledge that welding in a horizontal position will be the easiest and fastest way to weld. A flat position is not as taxing to maintain and the welding puddle will stay in place. Take some time to evaluate each project before beginning in order to make sure the majority of welds can be completed in this position. If a job calls for vertical welding, see this article about vertical welding. Core Wire Feeder Increases TIG Welding Speed: For professional welders hoping to speed up TIG welding, a core wire feeder will add filler metal through an automated process. Watch this video on how it works. This enables welders to work with both hands and to maintain a constant flow of wire into the welding puddle. Ed Craig at the Frabricator writes about the wire feeder process first developed in Europe, saying it is “suitable for all-position welding on materials of any thickness, the process addresses traditional GTAW limitations and can enhance both manual and automated TIG weld quality and productivity.” See additional info on MIG welder.

TIG welding filler wire and Mig welding wire from a spool are essentially the same composition except that mig welding wire often contains more silicon and that can actually be a good thing for TIG welding steel. Don’t hesitate to use steel or stainless steel mig wire if you run out of TIG welding filler metal. If its too small, double it up and twist it up in a cordless drill. Standard Tig wire for welding mild steel is E70S2 It seems like the standard mig welding wire off the shelf these days is almost always E70S6. The 2 and the 6 indicate the addition of silicon and deoxidizers in the wire. Stainless tig and mig wire is most often E308L unless you ask for something else.

Looking to purchase high quality pvc flexible conduit? Here are some tips and extra details helping you to make the best pick.

As our experience, there are several factors you need to take into consideration. Be sure to look at all available wires and cables when determining what conduit is best for your application. There are two kinds of flexible conduit, plastic flexible conduit and flexible metal conduit. Be sure to use the correct flexible conduit for job at hand. The flexible conduit fill is the maximum amount of space that the conductors running through the conduit can occupy. This would be your most important factor in determining the conduit to choose for a job.

The general procedure for using thin wall conduit is similar to the use of steel armor cable. The big difference is that conduit cannot be “snaked” through openings in ceilings and walls. You must have full access to joists and studs to install electrical conduit. So you probably won’t want to use it unless your local code requires it. IMC is typically used in hazardous locations, and in its stainless steel formulation, IMC is widely used in the food and beverage industry, in chemical plants, in cosmetic and pharmaceutcial industries, in refineries, in pulp and paper mills, in marine and coastal sites, in other corrosive environments. An advantage of IMC is its larger interior diameter compared with RMC of the same nominal sizes, making it easire to pull wires. Read extra details at Plastic Flexible Conduit.

Electrical metallic tubing, or EMT, is the most common type of conduit for exposed interior installations, such as in a basement or an unfinished garage or workshop. It is the lightest and thinnest of the rigid metal conduit types and comes in a few different diameters; 1/2-inch is the most standard size for household circuits. EMT is also called “thin-wall” and is relatively easy to bend with a tool called a conduit bender. EMT is permitted by the National Electrical Code (NEC) for dry and wet locations but requires special watertight fittings and connectors in wet locations. With proper installation, EMT raceway can serve as a circuit ground path and be used in place of a separate ground wire running inside the conduit.

The flexible metallic tubing (FMT) is made to give great flexibility and includes a metallic tube-like design. It really is very easy to route or shape to fit probably the most difficult areas. That is why it is great to utilize on the do-it-yourself projects where it is much better to not join multiple components of Stainless Steel Flexible Conduit together. Also, this kind of tubing does not feature any form of waterproof protection.

There are seven different types of conduit used commonly in residential and light commercial wiring. Rigid metal conduit, or RMC, is heavy-duty galvanized steel tubing that is installed with threaded fittings. It is typically used outdoors to provide protection from damage and can also provide structural support for electrical cables, panels, and other equipment. RMC is sold in 10- and 20-foot lengths and has threads on both ends.

I like welding so today’s subject is : Top online provider to purchase span gas in UK. The shielding gas does more than protect the finished weld from the effects of oxygen and nitrogen in the atmosphere. It affects the weld’s bead shape and size and its porosity and fusion, as well as the welding speed and amount of spatter. Choose your gas wisely and you’ll achieve strong, tough and corrosion-resistant welds; select poorly and you affect performance: delivering welds that are never quite good enough.

Safety: While argon is a good fit for a variety of welding jobs, it can be a safety risk. As with any gas work, there are steps to take to prevent causing an accident. Argon is stored in high-pressure tanks, and although its inert qualities mean that it doesn’t easily react to other chemicals, it is essential to be fully trained in handling and transporting gases to minimise the risk of accidents and hazards. The risk of gas leaking or spilling needs to be taken seriously; gas should be stored in a well-ventilated room. Argon is colourless and odourless so ensuring ventilation is available and that tanks are sealed adequately is critical. Read extra info on Span gas bottle.

Tests have shown that the relatively narrow cross section of the pure argon shielded weld has a higher potential for gas entrapment and, consequently, can contain more porosity. The higher heat and broader penetration pattern of the helium/argon mixtures will generally help to minimize gas entrapment and lower porosity levels in the completed weld. For a given arc length, the addition of helium to pure argon will increase the arc voltage by 2 or 3 volts. With the GMAW process, the maximum effect of the broader penetration shape is reached at around 75% helium and 25% argon. The broader penetration shape and lower porosity levels from these gas mixtures are particularly useful when welding double-sided groove welds in heavy plate. The ability of the weld bead profile to provide a wider target during back chipping can help to reduce the possibility of incomplete joint penetration that can be associated with this type of welded joint.

MAG welding with a carbon dioxide shielding gas or shielding gases containing high proportions of carbon dioxide, e.g. 80%Ar/20%CO2 does not usually present an exposure problem to CO or to any CO2 generated by the process. However, a CO2 asphyxiation problem could arise as indicated above. Similar comment can be made about gas shielded FCAW.

The normal gas for TIG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. In some cases, nitrogen (N2) and/or hydrogen (H2) can be added to achieve special properties. For instance, the addition of hydrogen gives a similar, but much stronger, effect as adding helium. However, hydrogen additions should not be used for welding martensitic, ferritic or duplex grades. Alternatively, if nitrogen is added, the weld deposit properties of nitrogen alloyed grades can be improved. Oxidizing additions are not used because these destroy the tungsten electrode.

Quad gases are mainly used within Marine environments. Quad gases are a four gas mix. Supplied in a range of lightweight cylinders and made from aluminum. Both reactive and non-reactive mixtures are available. Source: https://www.weldingsuppliesdirect.co.uk/industrial-gas/specialist-gases.html.
