    2020-10-1 · 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.

Mr. William Magenau gives analyses of both, which support this statement. As to the forms or combinations of the various constituents, it has been generally assumed by the authorities that the metals, gold, silver, copper, etc., are present in the metallic state. A few writers have suggested that the black precipitate may be an intimate combination of gold with something else. Gage thinks it is a double cyanide of gold and
