Finding Better Ways to Mine for Gold General Kinematics

Cyanide has made it possible for mining companies to mine low-grade ore bodies for microscopic flecks of gold and silver, and still turn a profit. In gold mining, cyanide solution is sprayed over vast heaps of crushed ore that is spread atop giant collection pads. The cyanide dissolves the gold from the ore as the solution trickles through the Carbon and Resin Technologies for Gold Recovery SGSThe ore is crushed, finely ground and mixed with the cyanide leach solution to form a slurry in an agitation tank. The activated carbon is introduced into the slurry and then removed by screening once it is fully loaded or “pregnant” with gold.
