The Metallurgy of Cyanide Gold Leaching – An Introduction ...

2014-10-20 · Refractory Ores/Solid-Solution Gold: In some ores, Au can be locked inside the sulphide mineral matrix of the ore (so called solid solution), and the cost for the energy required to grind and liberate is simply too high to be viable. These are “refractory ores” and require a chemical, not simply physical, process to liberate gold from the surrounding rock.
