Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.

The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper.

gold mining separation by crushing Gold Crushing
Gold ore separation uses comminution techniques to break down the excavated rock, but the material hardly looks like a lustrous yellow-orange metal. In order to properly free this rich element from the rock, the crushing stage has to be followed by a chemically active stage, such as the cyanidation process or the carbon in pulp release method.

concentration process should be conducted at as coarse a crush size as possible while minimizing losses of pay metals. Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals.
