Impurities are sometimes removed by froth flotation or mechanical processing. The mills produce crushed or finely ground talc that meets customer requirements for particle size, brightness, composition, and other properties.
11.26 Talc Processing 11.26.1 Process Description1 9 Talc, which is a soft, hydrous magnesium silicate , is used in a wide range of 2 2 industries including the manufacture of ceramics, paints, paper, and asphalt roofing. The end uses for talc are determined by variables such as chemical and mineralogical composition, particle ...
watering cyclones. The project process flowsheets shown in Figures 3.3 and 5.2 were developed for better coordination of the project. The process flowsheets effectively summarise the steps that were taken to achieve the objectives of the project. Pre flotation of talc prior to flotation of PGMs was tested to compare the two methods and
Talc: Part of 19 Sub A Flotation Cells floating talc. Result: A concentrate approximately 94% talc produced at the rate of ¾ tons per hour. Flotation produces a uniformly pure product at a low cost per ton of ore processed and in addition recovers talc which cannot normally be recovered by dry processes.

Flotation is the preferred concentration technique to remove impurities from talc Kho and Sohn, 1989). Various factors that control the flotation process of talc include particle size, pH values, collector dosage, depressant dosage, pulp density and frother dosage which were
