(1) Concentrating Ores by Flotation (2) The Flotation Process
The practical application Of flotation methods is only about thirteen years old, and already the quantity of ore treated by them must amount to little, if any, less than 30,000,000 tons.

flotation ore dressing Britannica
flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity

Flotation of gold and gold-bearing ores ScienceDirect
2005-1-1 Flotation of copper–gold ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold
