Silver Gold Recovery Flotation Process

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class ...
