Gold Refining

Gold Refining

Have you ever heard of the term gold refining? Do you know what it means? If not, then you have come to the right page where you will know some information of what gold refining is, what is its use, and what can it do in our industry.

Gold refining is actually the last stage of processing gold. Gold is a precious metal that is used to making fine jewelry, coins, and more. Refining the gold involves taking away all of the excess impurities that will leave the gold to its purest form. This happens when the gold is melted. During the molting process, gold refiners will try to remove impurities as well as other metals (semi-precious) that are mixed with gold, by using soda ash and borax, which they normally add in the melted gold. These chemicals have the ability to separate gold from other metals and impurities, so that the end product will be at least 99.9% gold.

The next process that will happen after gold refining, will actually depend on how this precious metal will be used. If for instance that gold is going to be used to make fine jewelry, gold in its purest form might not be a good fit, since 99.9% gold is too soft, which will not be able hold precious or semi-precious stones or will not be able to hold its form, after the final detailing of the goldsmith. So what goldsmiths do when using gold to make fine jewelry, is to turn it into an alloy, which means they will be mixing different metals to turn it into different colored gold.

Just to give you an example, the very popular white gold that is normally used for engagement rings, is a mixture of nickel and gold. Sometimes, they also use silver to make white gold, but most of the time, goldsmiths will use nickel, due to its nice combination with gold. Gold is also measured depending on its Karat. The higher the gold content is than the mixed metal, the higher the karat is. Preference for gold karat somehow depends from culture to culture. For instance, People in India would like their gold to be at least 91.75% pure, which is 22 karats. But people in the United States prefer 14 to 18K gold because gold at this form provides nice durability, hardiness that cannot be dent, and affordability too.



With e-waste processing, we can be sure that there will be more resources for making future electronic devices, because we are actually helping by preserving the raw materials that are sourced from nature, in order to make components and other electronic devices. For instance, precious metals are mined not only to make fine jewelry. They are also used by electronic companies to make chip boards and mother boards, in order to make the component and electronic gadgets work. By recycling, we preserve precious metals, so the demand will not be as high.

With an e-waste processing, people can give their electronic gadgets to refineries, in order to extract the metals, and use it for making new electronic devices. You, on the other hand benefit as well, because the extracted metals are actually paid, depending on the amount and quality of precious metal that was obtained or yielded from your device.

Another benefit of e-waste processing is that you are eliminating the possibility of the chemicals and harmful toxic wastes coming from electronic scraps that can contaminate the environment, which can result to illnesses or diseases to people. Electronic wastes should be disposed properly and practically through e-waste processing.

Catalytic Converter

Catalytic Converter

You might think that old cars is useless and there is nothing else that you can do with it, but take them to the junk shop, just to clear up some space in your garage. Actually, your old car can still be beneficial. You can even make a good amount of money, out of catalytic converter recycling.

A catalytic converter is found in the exhaust of an old car. The nice thing about this is - you can source a good amount of precious metal from this thing, particularly platinum. Platinum is a valuable precious metal that can be sold at a good price. In fact, you can sell them easily online, to a number of precious metal refineries, so you can make cash conveniently, even without leaving your home.

To extract platinum from catalytic converters, you will have to use several methods that will require chemicals that can be dangerous without proper handling. So if you do not have the full knowledge for platinum extraction, it might be better to bring your catalytic converter for catalytic converter recycling, so they can do the job for you, and give you the amount of cash that is equivalent to the amount of platinum in your catalytic converter.

Mining Process

Mining Process

According to professional miners, there are three basic stages or steps that you have to consider, when you want to start mining precious metals, stones, minerals, and more.

The first step is to determine the place where you want to dig. This may sound easy, but in actual, you will have to create a comprehensive plan that will cover everything that you need, to make sure that you are going to get results that you want. Of course, planning will also cover safety and legality, because you cannot just go on digging on places you want without getting the permits and license to do it.

Next is that you have to determine the tools, equipment, and machines that you need, to extract the precious metals or stones from the mine.

Lastly, how will you be able to extract the tiniest form of gold in the ore? Do you know how to do that? Remember, there is value from that dust that you thought is not profitable.

These are the very basic steps of the mining process. Regardless of what you are mining, these steps will be able to help you get started and achieve the kind of results that you want.

Jewellery Machine

Jewellery Machine

Earrings, Ring, Necklaces, and more..have you ever wondered how these fine pieces were made? We all know that the beautiful fine jewelry that we wear to spruce up our outfit started from odd shaped precious metal pieces that went through a lot of processes from melting, refining, to molding and more.

Miners work hard to find the best precious metals on earth with quality that can speak of its own. These metals goes through refinement in order for goldsmiths to be able to use them in its purest form.

Gold is one of the most expensive precious metals that are turned into fine jewelry. The artistic hands of the goldsmiths will work wonders, and create fantastic jewelry pieces using some of the best jewelry machines that will help them form the metal according to their likeness and preference.

Jewelry machines will also make it possible for goldsmiths to work on delicate stones embedded in precious metals accurately. But above all, the machines will help goldsmiths work faster, while maintaining precision especially when create perfectly shaped fine jewelry pieces that will not just make the wearer beautiful, but also be very proud of what they are wearing.
