Parametric Optimization in Rougher Flotation Performance

Flotation is one of the most widely used techniques to separate valuable minerals from gangue minerals in the mineral processing, because of its ability to treat low-grade and complex raw materials in the fine particle size ranges [3,4,5,6,7].Froth flotation takes place in the presence of three different phases, including solid (particles), liquid (water) and gas (air bubbles).

Frothers Quadra Chemicals

Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water and air bubbles.

The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called potassium amyl xanthate (or the potassium salt of an alkyl

A Brief Review of Pulp and Froth Rheology in Mineral Flotation

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
