Diagnostic Leaching for Refractory Gold Ores SRKSilver processing Britannica

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 for goldA process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve This is called inquartation and the separating of silver and gold by leaching with nitric acid is referred to as parting
