Effect of grinding environment on galena flotation

In this study the effect of two types of grinding media in wet and dry grinding on the formation of hydrogen peroxide and galena flotation was investigated. Laboratory stainless steel ball mill (Model 2VS, CAPCO Test Equipment, Suffolk, UK) was used for grinding galena with mild steel and stainless steel media.

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. It has been described as "the single most important operation used for the recovery and upgrading of

Introduction to Mineral Processing

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation.
