flotation reagents for gold and silver ores

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.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

01-01-2016  The depression of pyrite at high pH values can be overcome by the addition of more collector, stronger collector, and copper sulfate. Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9.
