Mineral Flotation

  • Chapter
Comprehensive Treatise of Electrochemistry

Part of the book series: Comprehensive Treatise of Electrochemistry ((CTE,volume 2))

Abstract

In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations. The flotation process involves crushing the ore to liberate separate grains of the various valuable minerals and gangue components, pulping the ore particles with water, and then selectively rendering hydrophobic the surface of the mineral of interest. A stream of air bubbles is then passed through the pulp; the bubbles attach to and levitate the hydrophobic particles, which collect in a froth layer which flows over the weir of the flotation cell.
