The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

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
