Cyanide Leaching Of Gold . Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Return To Process Plant
Thiosulphate leaching is a process that removes gold from gold bearing ores without the use of cyanide. Although not and type of equipment needed for a thiosulphate leaching flowsheet is very less robust than the cyanide leaching process, and is therefore more difficult to
This document provides a general overview of the use of cyanide in the gold and silver recovery and the location and design of the discharge equipment varies by vehicle. Solid briquette or flake cyanide is transported to the mine in drums, plastic bags, boxes, returnable bins and ISO-containers. the leaching process may also be modified
