Lime in Flotation and Recovery Processes Graymont

Lime in Flotation and Recovery Processes Both quicklime and hydrated lime are widely used in the flotation or recovery of non-ferrous metals, including copper, zinc, nickel and lead-bearing ores. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution.
