Processing Of Gold And Iron

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."
