cyanide leaching of gold cil ccd and destruction

A sodiumcyanidesolution is commonly used toleach goldfrom ore. There are two types ofleaching: Heapleaching: In the open,cyanidesolution is sprayed over huge heaps of crushed ore spread atop giant collection pads. Thecyanidedissolves thegoldfrom the ore into the solution as it trickles through the heap

    Dec 01, 2020· Previous studies have shown thatcyanide-free glycineleaching of goldis limited by slow kinetics and so is only likely suitable for heap, vat and in-situleaching. The addition of a very low dose ofcyanidecan increase the rate enough for tankleaching, but this does not completely solve the environmental issues associated withcyanide
