Feb 23 2009 At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums the ore is ground to a fine slurry or powder. Next mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a

Flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mine has low beneficiation cost. Application Gold Flotation Process is use to process fine gold sulfide gold-containing quartz ore multi metal gold-containing sulfide ore and carbon-containing ore.
Once extracted the gold is refined with one of four main processes floatation amalgamation cyanidation or carbon-in-pulp. Each process relies on the initial grinding of the gold ore and more than one process may be used on the same batch of gold ore. Mining
