One would need to know that there are a number of materials that yield pure silver, gold, and platinum when refined. 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 to make sure that he or she has the right information, equipment, and supplies to get it right. Among the materials one can refine as an individual include electronic scrap such as circuit boards, CPUs, RAM, pins among other components. It would also be possible for one to rely on coins, jewelry and bullion as well in his or her refining of precious metal. One can also refine catalytic converters which tend to be an excellent source of platinum metals such as rhodium and palladium. One can also process gold nuggets and black sand as well as jeweler waste which includes floor sweeps, polishing sweeps, bench sweeps, and grindings. One can also refine the x-ray film with the intention of extracting silver in it.
Where one has the material to extract the precious metals from, one would then need to make sure that he or she has the right tool and the procedure. In refine precious metals, one may need either salt water or acid for his or her process to be successful. It is also essential for one to note that both methods work equally. 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 only need to master the electrolytic process or the chemical process. The electrolytic way tend to be perfect but tends to yield some little fumes.
Salt water can be used to refine gold where one uses a very simple procedure. One would simply need to connect a wire to the car battery charger and then tie the metal in question using the wire. 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. The metal tends to dissolve at a rate of about an ounce every hour.
One would need to add a precipitant such as quadratic once the dissolving is done. One would have be sure that the resulting gold is 99.95% pure gold. One would also need to know how to refine gold with acid a method traditionally known as aqua regia or royal water. In that line, one would need to make sure that he or she knows of a website from which he or she can get detailed information on how to refine precious metals like a pro.
