the ary process for gold mineral processing

Gold Geoscience Australia

The first stage of processing gold ore is crushing. The gold then needs to be separated from the resultant powder. Coarse gold may be removed by gravity concentration. The powder is mixed with water, the gold sinks and the other wastes are washed away. Fine gold in crushed ore will be processed differently depending on the nature of the gold ore itself. Free milling ore is the name for when
