Froth flotation - Wikipedia

Deze pagina vertalen

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.

1-1-2020 · It is well documented that surface oxidation of copper sulphide minerals has some detrimental effects on their flotation performance. However, little work has been done to quantitatively relate surface oxidation to flotation performance, which makes it inherently difficult for processing plants to optimise flotation conditions for oxidised ores.
