  • Finding Better Ways to Mine for Gold General Kinematics

    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 heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the stacks until the ore is depleted.
