There are a number of locally available materials that yield gold, silver, and platinum when refined. One would also need to know that it tends to be very easy for one to process precious metals even when one is to use locally available metals. As long as one has the right information, raw materials, and equipment, he or she would not need to worry about how to process a given precious metal. One would utilize precious metals found in CPUs, circuit boards, RAM, PINS, among other sources. One can also refine jewelry, coins, and bullion. It would be possible for one to use catalytic converter to acquire platinum metals such as palladium and rhodium. It would also be possible for one to refine precious metals by utilizing of gold nuggets, black sand or even jeweler waste. It would also be modest for one to know that it is possible for one to refine silver from the x-ray film.
Where one has the right tools one would need to know the procedure of refining gold and platinum for example. In refine precious metals, one may need either salt water or acid for his or her process to be successful. Whether one has acid or salt water, he or she would need to know that the two procedure work perfectly well. It would also be essential for one to note that refining precious metals at home tend to be easy, effective and definitely cheap. One would only need to master the electrolytic process or the chemical process. One would expect little fumes especially where he or she opts to go for the electrolytic process of refining precious metals.
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. Where one is doing a bigger unit, he or she would need to make sure that he or she uses this model. One would then turn on the current through the wire and then into the acid. One would be sure that about an ounce of metal would have to dissolve after every one hour.
One would also need to make sure that he or she has a precipitant such as quadratic. Pure gold tends to turn into solid metal with all other metal impurities remaining dissolved. One would also need to know how to ensure motivation of using acid instead of salt 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.
