Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Effect of pH on the Recovery and Grade of Base Metal

[10]. The use of co collectors or promoters in flotation is well established [11]. One of the most important aspects of froth flotation is the formation of a froth in which the valuable minerals are retained for further up grading. Thus the presence of a surface-active or frothing agent, either as a

Effect of Clay Rheology on Flotation of a Refractory Gold Ore

Oct 10, 2016· The results showed that bentonite clay adversely affects floatability of pyrite while kaolinite clay had a lesser influence on flotation of pyrite. The addition of Ca2+ ions to the pulp containing bentonite modified the rheological characteristics and in turn improved the pyrite flotation.
