Froth Flotation an overview ScienceDirect Topics

Froth flotation is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed. A concentration of 25–30% is suitable for economical smelting of copper.

1 Froth Flotation Fundamental Principles

2009-8-27  The properties of raw mineral mixtures suspended in plain water are rarely suitable for froth flotation. Chemicals are needed both to control the relative hydrophobicities of the particles, and to maintain the proper froth characteristics. There are therefore many different reagents involved in the froth flotation process, with the selection of reagents depending on the specific mineral mixtures being treated.

Effect of reagents and minerals on froth electrical

Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide a selective levitation of the solid particles. It is a cheap and most extensively used process for concentrating ores. (Crozier 1992).
