Different machines to meet all needs
An old and well-established process, the Wohlwill method is widely used in major gold refineries, often in conjunction with the Miller process. (For typical jeweler's scraps and wastes, a preliminary refining step, such as the Miller or inquartation process, is required.)

For the first time ever, gold processing can be done with a high level of confidence and safety, from a very small jewelry business to medium scale refinery. The process is simple and easy. By using our REFINEIT system, all the user has to do is melt the gold in an ingot, submerge the gold in the gold refining equipment we provide, then wait.

The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). It was invented by Francis Bowyer Miller ( patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides ...

Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.
