Copper wire recycling Bare bright copper cable scrap






Hello my friends Copper Wire Recycling
Important Things You Should Know About Copper Cable Recycling
Copper is a non-ferrous metal, meaning that it's a metal that is not derived from iron. It is commonly used in electrical wires and pipes for plumbing in its purest form, without any other metals or alloys. Demand for copper is increasing, commensurate with its usage today, thus, recycling copper can generate profit for you. The price you'll receive for copper will be based on what the copper was used for and its condition.

 Another common recycling equipment for copper is copper wire/cable stripping machine. Copper wire stripping machine is especially suitable for stripping thick wires and cables of single-strand or multi-strand. More labor-saving and less energy -consumption. The popular cable stripping machine can process wire/cable with diameter from 1-90mm. Copper wire recycling Bare bright copper cable scrap. scrap bare bright copper.


Copper facts you might not know
Did you know copper is nearly 100 percent recyclable? More than half of the copper consumed in the U.S. is from recycled scrap.

Almost 80 percent of copper produced in the world is still in use, and it can continue to be recycled without any changes to its properties. In fact, it retains 95 percent of its original value.

It’s also worth mentioning that copper should never be burned in an open fire. By processing the following scrap through a quality distributor, you minimize your impact on the environment for the betterment of the communities in which you live and work

How Much Gold is in Smartphones and Computers?



How Much Gold is in Smartphones and Computers?

Most people picture copper when they think about how electricity is conducted, probably because it’s the most common conductor. Silver is actually the best conductor, followed closely by gold. Copper is cheaper than precious metals, but it’s also much slower in transporting electrons than its glamorous siblings. In the world of computing and communications, speed is more important than cost, so copper remains relegated to construction and pennies.
And as fast a conductor as silver is, it corrodes or tarnishes easily whenever it comes in contact with water — even with humid air. Corrosion is to electrons what fresh road tar would be to Olympic runners.
Gold, on the other hand, is highly corrosion-resistant. So, while it’s not as fast as silver, it doesn’t fall apart like silver and is many times faster than copper.
There is intrigue brewing in the electronics industry, though. Some manufacturers are looking at how quickly people upgrade their electronic devices to learn whether using gold is necessary.
If consumers replace their devices faster than silver can break down, electronics companies may decide to depose gold as the ruler of conductors to fatten their margins. Why pay to install high-quality materials when so many buyers crave novelty more?
Were this trend to take hold, devices would have shorter life spans, which would stifle resale markets and, not coincidentally, increase the flow of unwanted goods to recyclers.

Uses of Gold in Computers

Gold is used in many places in the standard desktop or laptop computer. The rapid and accurate transmission of digital information through the computer and from one component to another requires an efficient and reliable conductor. Gold meets these requirements better than any other metal. The importance of high quality and reliable performance justifies the high cost.
Edge connectors used to mount microprocessor and memory chips onto the motherboard and the plug-and-socket connectors used to attach cables all contain gold. The gold in these components is generally electroplated onto other metals and alloyed with small amounts of nickel or cobalt to increase durability.

Uses of Gold in Electronics

The most important industrial use of gold is in the manufacture of electronics. Solid state electronic devices use very low voltages and currents which are easily interrupted by corrosion or tarnish at the contact points. Gold is the highly efficient conductor that can carry these tiny currents and remain free of corrosion. Electronic components made with gold are highly reliable. Gold is used in connectors, switch and relay contacts, soldered joints, connecting wires and connection strips.
A small amount of gold is used in almost every sophisticated electronic device. This includes cell phones, calculators, personal digital assistants, global positioning system (GPS) units, and other small electronic devices. Most large electronic appliances such as television sets also contain gold.

One challenge with the use of gold in very small quantities in very small devices is loss of the metal from society. Nearly one billion cell phones are produced each year, and most of them contain about fifty cents worth of gold. Their average lifetime is under two years, and very few are currently recycled. Although the amount of gold is small in each device, their enormous numbers translate into a lot of unrecycled gold.

Metal Melting Point Temperature

Metal Melting Point Temperature

We have the melting points in Fahrenheit and Celsius of most common metals listed here. We do not carry all of these metals, but provide them as reference information.
The melting point (or, rarely, liquefaction point) of a solid is the temperature at which a sustance changes state from solid to liquid at atmospheric pressure. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at standard pressure. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point.

Gold from CPU Intel Pentium III Xeon





Hello, friends
Today I have an Intel Pentium III Xeon CPU.
The processors can boost multi-processing server performance by more than 30% versus existing systems using the Pentium III Xeon processor. Intel Pentium III Xeon family is a family of high-performance processors for high-end workstations and servers. introduced in March of 1999. I think the CPU will have a lot of gold when looking at the size and is High performance CPU Unfortunately, my Intel Pentium III Xeon CPU has a little gold at the connection point with the Gold Fingers cpu socket. And there is no gold wire inside the cip cpu. Work experience will teach us and do not despair.
Computer motherboard and other electronic circuit boards can also contain rich gold content made up of gold-plated circuit traces, edge fingers, connectors, Integrated Circuits, transistors, & memory chips. There is very little profit from extracting the gold content found in most computer chips and electronic components yourself unless you have significant quantities of them to be processed. Refining Gold & other precious metals (including silver, palladium & platinum) from CPU's & electronics is typically not profitable unless it's done professionally and in large quantities on a large scale; when processing just a few items the cost is often higher than the value of the gold that is reclaimed. More importantly, the process of refining gold involves working closely with hazardous materials including nitric and hydrochloric acids, as well as Mercury, and should only be performed safely by experienced Gold refiners.

gold recovery from cell phone




Hello friends, Today I am going to take a breakdown of the components of old mobile phones that have gold.

Socket Sim is a good piece of gold plated. You can use the clamp to separate this part. For a gold-plated keypad, you may need a gold stripping. For touch screen phones, you may not find a keypad. And do not get gold in this piece. You have to observe. The gold will be stacked on the back. In some cases, you may find gold chips in their electrical circuits. That's good For gold miners. In gold-rich ore deposits, there are concentrations of gold at one or two parts per million, That equates to 1g or 2g per tonne. And the idea that 41 handsets contain 1g of gold stems from a UN report on electronic waste. a tonne of old phones (weighed without their batteries) yields about 300g of gold. But the business case may not be as clear as the commissioner claims. At current gold prices, the amount in your handset is worth less than £1 ($1.67). Ic Chips are components that have gold wire inside. You may use a hot air gun to do it like me, or use pliers to separate it out. May have to use force And please be careful of safety Use various protective equipment. When you separate the devices Of mobile phones As the example I show You can extract gold. According to the methods I have presented in the last video. To learn more. #GoldRecoveryCellPhone #RecoveryCellPhone #GoldCellPhone

How to make pure gold easy from gold alloy


Hello, friends Today i have How to make pure gold easy from gold alloy. Gold recovery use nitric acid.
It is a method of making pure gold as in the past and is popularly used in ancient times Up until now. Extraction of gold by smelting is done with metallic mix gold. Scrap gold, jewelry gold, with gold components for more than 25%. Not suitable for metal gold plated surfaces. Ratio Gold alloy 1 Copper 1 Lead 2 1. Melt Metal all together. The copper melt first. put the gold and lead. homogeneous melt. 2. Pour the melted gold into the water. broken down into smaller ones. To make it easier to use nitric acid to dissolve the metal is not gold. Nitric acid mixed with water, ratio 1 to 1 Boil nitric acid with 80 Celsius Boil until no air bubbles. Clean the gold powder with hot water or bring to a boil. Dry gold powder In some cases. If gold is mixed evenly in the alloy and at a low enough concentration, you can use plain nitric acid to dissolve away impurities. However, if the gold is more pure (or is an external plating), what actually happens is that the nitric acid tries to dissolve everything, but the gold blocks it from coming through. In that case, you purify an outer layer, but the internal layers are not pure because they are protected by an insoluble layer of gold. To fix this, we can add hydrochloric acid to the nitric acid (so the gold is also dissolved) and then selectively precipitate out the gold. Thank you very much #GoldNitricAcid #GoldAlloy

HOW PURE IS YOUR GOLD?


The purity of gold is defined either in karats or fineness. A karat is 1/24 part of pure gold by weight, so 24-karat gold is pure gold. To find the percentage of gold in an object when the purity is stated in karats, multiply the number of karats by 100 and divide by 24.
24 karats = 100 percent gold
22 karats = 91.75 percent gold
21 karats = 87.5 percent gold
18 karats = 75 percent gold
14 karats = 58.5 percent gold
12 karats = 50.25 percent gold
10 karats = 42 percent gold
9 karats = 37.8 percent gold
8 karats = 33.75 percent gold

How to refining gold scrap into pure gold bar 24k | aqua regia process at home




Hello, friends How to refining gold scrap into pure gold bar 24k aqua regia process at home. Today I have a way to do pure gold bars 24k from gold scrap. sometimes you may want to make some extra money by refining your own gold at home, or you may be a jeweler who wants to refine gold in-house. There are multiple ways to refine gold on a small scale as long as you take appropriate safety measures. This article will teach you to refine gold using the aqua regia method. Start by reducing the size of gold to smaller. Melt gold, pour gold while melting through a 2 mm sieve into the water. Reducing the size of gold to smaller Will help in the process of aqua regia to make gold into the solution more quickly. aqua regia is composed of 2 chemical substances, 1 nitric acid, 3 hydrochloric acid mixed together. Ratio between gold alloy and acid aqua regia Gold alloy 50 grams, using acid aqua regia 200 ml From my experiment When gold alloy Was made into a solution at a temperature of 90 Celsius to reach saturation point fit. should neutralize easy to make gold precipitation. Operational safety Wear the protective clothing could include gloves, protective eyewear, a mask, a long sleeved shirt and long pants. Take precautions to avoid exposure by the principal routes, that is, contact with skin and eyes, inhalation, and ingestion. Proper ventilation is required This precipitant has a very strong, pungent, acid odor and is corrosive. Use sodium metabisulfite precipitate gold out of a aqua regia solution. You will get gold sludge powder looks like mud. Sodium metabisulfite (also known as sodium bisulfite) is an affordable and effective selective precipitant for gold. This chemical can recover up to 99.95% of pure gold when the precipitated gold is thoroughly rinsed. It works well even at room temperature. I will show you the strange change of gold mud. Use sodium mixed with water slowly added to the gold solution. You will see the formation of gold mud. Precipitated gold particles vary in size, but tend to be small and float easily in the rinse water. For this reason, special care must be taken to avoid accidentally pouring off gold with the rinse water. Use hot water to clean the sludge powder Looks like mud. Boil gold mud and hydrochloric acid 90 celsius 10 minutes. Use hot water to clean the sludge powder Looks like mud 3 times. You will get gold sludge powder Make dry use low heat To avoid splashes. Melted into cubes. Sprinkle a little borax powder. I will make a pure gold bar for beauty. I get a beautiful pure gold bar, weighing 46 grams. I hope you like our videos.

mercury and aluminum reaction amalgam | mixing mercury and aluminum reaction




Aluminum + Mercury = Aluminum amalgam Aluminum amalgam is a chemical substance formed by a solution of aluminum with mercury.
Reactivity Aluminium in air is ordinarily protected by a molecule-thin layer of its own oxide. This aluminium oxide layer serves as a protective barrier to the underlying aluminium itself and prevents chemical reactions with the metal. Mercury coming into contact with it does no harm. However, if any elemental aluminium is exposed (even by a recent scratch), the mercury may combine with it to form the amalgam. This process can continue well beyond the immediately exposed metal surface, potentially reacting with a large part of the bulk aluminium before it finally ends. The net result is similar to the mercury electrodes often used in electrochemistry, except instead of providing electrons from an electrical supply they are provided by the aluminium which becomes oxidized in the process. The reaction that occurs at the surface of the amalgam may actually be a hydrogenation rather than a reduction. The presence of water in the solution is reportedly necessary; the electron rich amalgam will oxidize aluminium and reduce H+ from water, creating aluminium hydroxide (Al(OH)3) and hydrogen gas (H2).[contradictory] The electrons from the aluminium reduce mercuric Hg2+ ion[clarification needed] to metallic mercury. The metallic mercury can then form an amalgam with the exposed aluminium metal. The amalgamated aluminium then is oxidized by water, converting the aluminium to aluminium hydroxide and releasing free metallic mercury. The generated mercury then cycles through these last two steps until the aluminium metal supply is exhausted.


2 Al + 3 Hg2+ + 6 H2O → 2 Al(OH)3 + 6 H+ + 3 Hg Hg + Al → Hg·Al 2 Hg·Al + 6 H2O → 2 Al(OH)3 + 2 Hg + 3 H2 Due to the reactivity of aluminium amalgam, restrictions are placed on the use and handling of mercury in proximity with aluminium. In particular, large amounts of mercury are not allowed aboard aircraft under most circumstances because of the risk of it forming amalgam with exposed aluminium parts in the aircraft. Even the transportation and packaging of mercury-containing thermometers and barometers is severely restricted. Accidental mercury spills in aircraft do sometimes result in insurance write-offs.



Safety reminders: Do not try this at home. Mercury is a neurotoxin and should only be handled by a professional. Protection, extreme caution, and safety procedures are required. Also: “The reaction itself and the waste from it contain mercury, so special safety precautions and disposal methods are needed.” mercury and aluminum reaction amalgammercury and aluminum reaction amalgam | mixing mercury and aluminum reaction. #MercuryAndAluminum #MercuryAluminum #MercuryAluminumAmalgam

What happens when aluminium meets mercury? The answer will surprise you. video of an mix aluminum and mercury. Aluminum is normally protected by a thick oxide layer, but the formation of the amalgam disrupts it. It allows fresh aluminum to react with air to form white aluminum oxide. As the oxide grows, it forms as these cool white fibers.
