Flotation | SpringerLink
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.

Silver Gold Recovery Flotation Process
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 gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class includes copper, lead, lead …

Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration, flotation remains the most cost-effective bene ficiation method. Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm.
Improving fine copper and gold flotation recovery: a plant evaluation
