SILICONE GLYCOL COLLECTORS IN THE BENEFICIATION OF FINE COAL BY FROTH FLOTATION Abstract A froth flotation process for the beneficiation of fine coal is disclosed which employs as a collector a waterdispersible polyorganosiloxane or a mixture of waterdispersible polyorganosiloxanes which contain organic radicals selected from the group consisting of polyethylene oxide and .

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.

The beneficiation of cassiterite fines from a tailing slime in the Datun concentration plant was studied through a froth flotation process, with the chemical scheme of benzohydroxamic acid as collector, lead nitrate as activator, and pine oil as frother. It was found that tin values are mainly ...

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

Ore Beneficiation by Froth Flotation. ... If they are subjected to flotation soon after grinding they will tend to stick to bubbles and to be raised to a froth. Silica and gangue are wetted by water and will tend to sink. The natural differentiation of valuable mineral from gangue in this way is very good, but the "sticking" of ...

The tailings of the beneficiation plant described in chapter (Itamarita de Minas) still contain bauxite, which can be separated by reverse froth flotation (flotation of the quartz and depression of the bauxite), using starch as a depressant and amine as a promoter at a pH of approx. 10.
