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."

Mineral processing

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
