Beneficiation of the gold bearing ore by gravity and flotation

Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and …

Notes on Method of Froth Floatation

Froth floatation is perhaps the most well-known method for eliminating minerals from rocks and materials. Frost floatation separates economically significant minerals from different minerals and pollutants in metal/mineral handling. The minerals are gathered on the outer layer of a thick layer of called a "froth layer.".

[PDF] Froth Flotation – Fundamental Principles

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase.
