An overview of reverse flotation process for coal

The idea of reverse flotation for coal started with the first patent done by Eveson in 1961 on bituminous coal in which shale i.e. the mineral matter was floated and reported in the froth phase while the clean coal was depressed and remained in the suspension. The concept was further developed for the selective removal of pyritic …


The effects of partially replacing amine collectors by a …

In anionic flotation, fine-sized crystalline iron oxides, such as hematite or siderite, are floated away from siliceous gangue material such as quartz or chert. In cationic flotation, silica or the gangue material is floated and the value-bearing minerals are removed as underflow, referred to as reverse flotation [3, 5].
