copper mining goldextractionprocess com materia

Gold extraction process. Copper is a nonferrous metal, meaning that it's a metal that is not derived from iron. It is commonly used in electrical wires and pipes for plumbing in its purest form, without any other metals or alloys. Demand for copper is increasing, commensurate with its usage today, thus, recycling copper can generate profit for

Extraction of Gold

The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles."
