Gold Cyanidation Process
The quantity found in solution will furnish an estimate of how much lime will be needed for making up the cyanide extraction test. Generally, a residual strength of 0.05% CaO will indicate a suitable quantity of lime for an all-gold ore, and 0.1% for a silver or silver-gold ore.
