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. Among the materials one can refine as an individual include electronic scrap such as circuit boards, CPUs, RAM, pins among other components. 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. One can also process gold nuggets and black sand as well as jeweler waste which includes floor sweeps, polishing sweeps, bench sweeps, and grindings. 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 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. 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 start by hanging the metal on a wire which he or she should connect to a car battery charger and then immerse the metal into the salty water. 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 the metal would dissolve at a rate of about one ounce per hour.
It would essential for one to make sure that he or she adds quadratic which is supposed to act as a precipitant. Pure gold tends to turn into solid metal with all other metal impurities remaining dissolved. The part of gold left in the salt water would be about four parts of gold in every million parts of salt water. One would also need to know how to refine platinum using aqua regia as well something he or she can learn from the internet.
