The process is complete when purple fumes of gold chloride start to form, usually when the gold content reaches a purity of 99.6 to 99.7 percent. Any PGMs present are not removed, and further refining is necessary if pure gold is required. The typical gold purity achieved by this process is 99.5 percent, with silver as the main impurity.
22-11-2016· Complete the process of electrolysis. You will dump your prepped waste materials into the electrolysis tank and allow the silver to be leached out by the chemical reactions created by the caustic solution and the electrical current.

Process Silver was first obtained in sixteenth-century Mexico by a method called the patio process. It involved mixing silver ore, salt, copper sulphide, and water. The resultant silver chloride was then picked up by adding mercury. This inefficient method was superseded by the von Patera process.
The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.
