The cyanide gold extraction process also suits for copper leaching, zinc leaching, sliver leaching, etc.At current gold prices this is worth about 400. Both smelter treatment charges and oxidation or bio-leach costs are around 200t of concentrate so a minimum GSR for effective downstream processing is 0.5, but clearly this is a function of gold price. A lower GSR can be tolerated if the flotation concentrate is amenable to direct cyanide ...
