Froth flotation - Wikipedia

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti

Coal Flotation | SpringerLink

Abstract. Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from run-of-mine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water.

Beneficiation of Fine Coal: Froth Flotation Efficiency

Froth flotation has been used extensively in the past to beneficiate fine coal (nominal minus 0,5 mm) in Natal, as well as at Grootegeluk in the Waterberg coalfield. In most of these cases, the fine coal produced from the froth flotation plants was destined for use as either a coking coal or a blend-coking coal.

Pyrite is removed from coal by means of a two-stage froth flotation process. In the first stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the second stage, the froth product from the first stage is subjected to froth flotation using a coal flotation depressant and a pyrite flotation collector, thereby removing a substantial proportion of fine pyrite.
