ROCK CRUSHING METHOD AND SEPARATING GOLD
Oct 13, 2017In 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. These reagents chemically separate the gold from the ore, so they’re every bit as essential to a mine’s operations as any primary crushing equipment.
