gold refining systems - safe & simple - machines and equipment for gold and silver electrolytic, wohlwill and aqua regia refining, purification, processing, recovery
Traditionally, the resources necessary to refine, recycle gold, safely and effectively, have been available only to large scale jewelers and precious metal miners, refiners--seldom to small or medium-scale refineries and jewelry businesses, and never to individuals interested in buying scrap gold to turn it into a precious keepsake. That's all changed, though, thanks to Gold Refining Systems, Inc., a company devoted to helping jewelers and refiners of all sizes to refine, recover gold safely, efficiently, and with ease.
Our gold refining systems offer you what you need to refine gold of any kind-- whether its scrap gold, fine gold jewelry, karat gold, gold from mining, prospecting or gold of any other type. The system even works for other precious metals, including silver, platinum, and palladium. But what sets Gold Refining Systems, Inc. apart is our innovative technology:
For the first time ever, gold processing can be done with a high level of confidence and safety, from a very small jewelry business to medium scale refinery. The process is simple and easy. By using our REFINEIT system, all the user has to do is melt the gold in an ingot, submerge the gold in the gold refining equipment we provide, then wait. The next day, pure, 24-karat gold will be waiting!
Gold Refining Systems not only makes the gold refining, reclaiming process easy, but also clean and safe. By using our Safe Gold Refining Technology products, the jeweler or refiner eliminates the production of toxic fumes. Nothing like Aqua Regia, Miller process, inquarting - parting process, with large quantities of toxic fumes produced, toxic gases, boiling acids.
The gold refining systems we offer are cutting edge, and, unlike anything else on the market, they offer an effective alternative to commonplace refining processes like Miller, Wohlwill, Aqua Regia, and inquarting-parting. Our electrolytic machines take what is typically multi-step process dangerous process and turn it into a single-step procedure that can be done quickly, easily, and without the presence of dangerous or irritating fumes. Smelt your low karat gold, place in to the system, wash refined 24K gold, use it.
how to refine gold: 2 major techniques of gold refining process - superb electromachinery co., limited
The answer is very simple: We cannot use gold in its raw form. It is a precious, noble metal that comes in different forms: As an alloy of silver and platinum, an amalgam, as a part of a stone, or in scattered particles. Or you may even decide to refine your current piece of gold and convert it into another shape/form that will be more useful for you.
Gold must be refined from its alloys or amalgam forms in order to get the pure gold that you can use in whichever way you like. Several people think that their gold pieces are pure. That may not be true, because an alloy of gold and copper still have a brilliant shining color, but it lacks other chemical properties of gold.
Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.
Aqua Regia has been used to separate gold from other metals for a long time. It involves using Aqua Regia, which is a Latin word for royal water. Actually, Aqua Regia is a chemical solution which fumes, and it is corrosive in nature. It is either yellow or red in color. You can freshly prepared Aqua Regia by mixing concentrated hydrochloric acid with concentrated nitric acid.Aqua Regia gets its royal name from its ability to dissolve some noble metals such as gold and platinum. The diagram below explains the Aqua Regia gold refining process:
Since gold naturally occurs as an alloyin a mixture with other metalsa process such as Aqua Regia will be a good method to obtain gold in its purest form. The physical steps involved in this procedure are highlighted below:
I. The alloy consisting of gold and other metals is introduced/fed into the Aqua Regia system after it has been granulated and heated in an Aqua Regia solution.II. Treat the solution of gold + other metals with a reducing agent (sodium metabisulfite) and filter.III. You will obtain pure gold powder, separated from the solution of other metals.IV. Wash, dry, and granulate the gold powder.V. The final result will be your pure gold grain.
Since the purpose of the procedure above is to separate a pure gold from other metals, the same process can be used to obtain other noble metal such as silver and palladium.Here is the list of some of the equipment required to successfully carry out an Aqua Regia gold-refining process:
Aqua Regia system is one of the best approaches anyone can use to obtain pure gold grain and bars from other metals. This is basically a series of chemical processes (reactions). The actual chemical representations of this gold-refining procedure are provided below:
Step five: The dropping (sedimentation) of gold from the other metals happens in this step. And this step is completed by treating the solution with a reducing agent such as SO2, sodium metabisulfite, or other reactants. If you are using either SO2 or sodium metabisulfite (SMBS), the gold will not be reduced until the excess or all nitric has been eliminated.It is also possible to remove nitric by adding urea to it.
Aqua Regia is a well-known process for obtaining gold in its pure form. And the chemical reactions involved in this procedure are effective. The chemicals are available everywhere and not too expensive.However, the main disadvantage of this procedure is that permissions from the local authorities may be needed. This is because some of the chemical reactions may produce by-products that could have some destructive effects on the environment. This include toxic fumes and chemical by-products that may not be good for human health.
Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast gold ingot at 95% plus purity is used as the anode. The cathode (s) for this electrochemical procedure are small sheets of 24 Karat (pure) gold sheeting. When current is applied to the system, the electricity moves through hydrochloric acid, which is the electrolyte for this process. Then gold and other metals are deposited at the anode during the electrolysis, but the pure gold that has passed through chloroauric acid by ion transfer is deposited or plated on the cathodes.
The anode is dissolved during this process. And the cathodes are subsequently removed and melted into required shapes. It is also possible to sell the gold deposit on the cathodes as it is. However, if you wane cast a special shape in mind, a bar or a particular shape, it is advisable that you melt the gold first and pour it into specific machines, such as jewelry casting equipment, gold coin making machine, gold bar casting machine, etc.
Mostly, the gold obtained through gold electrolysis is usually very pure, almost 99.999%. In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold). This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatage.
As the best technique for getting the purest gold all over the world, gold electrolysis is widely adopted among some gold-making companies that value only the purest gold. It does not produce gaseous fumes and other unpleasant gases. Gold electrolysis requires small amount of chemicals and labor. It is, in fact, environmentally friendly.
However, it is a very expensive procedure because a permanent stock of gold is required to run the electrolytic process. Take for instance, for every gold produced through this method, 20% of it is lost on the anode. In other words, if you aim at producing 100kg of gold, you should make provisions for 120kg, because at the end of the process, 20kg will be plated or wasted on the anode, leaving you with only 80kg of gold (in case you have not previously made any plans for the loss of gold on the anode).
