It is possible to refine precious metals such as gold, platinum, and silver from some locally available materials. You may not yield the best results the time you do it but refining of precious metals tend to be very easy and one does not need any experience. One would only need the right equipment, supplies and definitely the right information so as to refine precious metals. Among the materials one can refine as an individual include electronic scrap such as circuit boards, CPUs, RAM, pins among other components. One as well can acquire precious metals from jewelry, coins as well as bullion. One can also refine catalytic converters which tend to be an excellent source of platinum metals such as rhodium and palladium. It would also be possible for one to refine precious metals by utilizing of gold nuggets, black sand or even jeweler waste. One can also refine the x-ray film with the intention of extracting silver in it.
Where one has the right tools one would need to know the procedure of refining gold and platinum for example. One would need to know that he or she may need salt water or with acid. Whether one has acid or salt water, he or she would need to know that the two procedure work perfectly well. Where one refines the metals for himself or herself, he or she would be sure that he or she would minimize cost, be sure of safety and also be sure that he or she will get what he or she wants. One would need to use either the electrolytic or the chemical process. The electrolytic way tend to be perfect but tends to yield some little fumes.
Apart from the material from where one is to extract gold, one would only need salt water. One would only need to hang the metal with the wire and then connect the wire in question to the car battery charger. Even when one has a lot of materials, he or she would need to make sure that he or she goes for this sample model. One would then need to turn on the battery charger allowing the electric current to run through the metal. One would be sure that the metal would dissolve at a rate of about one ounce per hour.
One would also need to make sure that he or she has a precipitant such as quadratic. One would be sure that pure gold would turn into metal while other materials would remain in the acid or salt used. One would also need to know how to ensure motivation of using acid instead of salt water. One can easily learn more about refining precious metals where he or she visits a reliable website for more.
