Rock gold mineral processing, how to extract "gold concentrate"?

Gold ore beneficiation is to extract gold concentrate from placer gold and rock gold through beneficiation methods.

The gravity separation process is mainly used for the beneficiation of placer gold.

The flotation method is generally used for fine-grained gold sulfide with good floatability. Ore, the mined sulfide gold ore is crushed to less than 20mm by a crusher, then ground to powder by a ball mill, and finally enters a flotation machine to flotate the gold-containing concentrate.
