Diagnostic Leaching for Refractory Gold Ores
The sulfuric acid leach residue is then subjected to cyanidation and a sample of the residue is assayed for gold. Stage 4: Leach residue from Stage 3 is reacted in a hot nitric acid leach to dissolve more resistant sulfide minerals, such as pyrite and arsenopyrite, and liberate any gold that might be locked in these minerals. The residue is then subjected to cyanidation and a sample of the residue is assayed .

Common gold ore mixed mineral processing process flotation process, gravity separation. In most cases, the application of cyanidation in quartz vein type gold ore is relatively common, the main consideration is the ore grinding fineness, pulp in the cyanide concentration, leaching time. At the same time, in order to reduce the amount of cyanide leaching operation, can adopt the technology of .

The residue is then subjected to cyanidation and a sample of the residue is assayed for gold. Stage 5: Leach residue from Stage 4 is subjected to a high temperature roast to remove any carbonaceous material and then subjected to cyanidation and the residue is assayed for gold. Any gold remaining is assumed to be locked in silicates or associated with fine sulfides.
