Improving flotation separation of apatite from dolomiteSep 01, 2020· Froth flotation is widely used as an effective method for separating apatite from dolomite. However, it is of difficulty to realize the efficient separation of apatite and dolomite using the traditional fatty acid collectors without any depressants due to their similar physicochemical properties.Cited by 34(PDF) Soap Flotation of Dolomite ResearchGateSoaps of mixed fatty acid origin or soaplight diesel oil (LDO) emulsion are used as collectors in the froth flotation of salt type minerals (for example apatite, fluorite, dolomite, etc.).Estimated Reading Time 5 minsDolomite flotation of high magnesium phosphate ores usingDolomite Flotation of High Magnesium Phosphate Ores
The froth flotation(7074) is a process for separating different solids based on their physicochemical nature. This process has permitted the mining of low grade and complex ores which would have been worthless if more conventional methods, like gravity concentration, were relied upon.

Nov 01, · At present, froth flotation is still the most recognized technology to obtain the magnesite concentrate product , . However, large amounts of carbonate minerals especially dolomite appearing in lowgrade magnesite ore complicate the selective separation of magnesite and dolomite, thereby causing great difficulties in obtaining highquality magnesite concentrate containing low calcium.

of flotation is to have the desired mineral in solution attach to an air or nitrogen bubble and form a froth layer, which is periodically scraped off and collected. Bastnaesite is a hydrophilic mineral, so collectors are required to make the mineral hydrophobic. The hydrophobic minerals can then attach to the air bubbles and form a froth.
