Gold Precipitation Methods - Mineral Processing & Metallurgy

In cyaniding most gold ores, the lime consumption is generally dictated by the requirements of effective settling and is almost invariably higher than necessary for the best precipitation. In cyaniding silver ores, a high alkalinity is needed to dissolve the minerals, and lime consumption for this purpose usually exceeds that needed for settling.
