A process applicable to different lithologies of phosphate ore with siliceous carbonated matrix from igneous or sedimentary origin rocks includes ore preparation by comminution through crushing, grinding, and de sliming, prior to apatite flotation. During flotation, ground and de slimed ore pulp with high concentration of solids, above 40%, is initially conditioned with
May 19, 2011 As said before, in the industrial flotation of phosphate ore, a selectivity ratio of about 4.0 between apatite and iron minerals and of 10 between apatite and silicate minerals are considered satisfactory. Additional requirements are a phosphorus grade of about 28–30% and an apatite recovery rate of more than 40%.
May 29, 2020 We estimate that a full scale production from Malmberget and Kiruna will produce around 400,000 tonnes of apatite concentrate annually, in two plants that will be of similar size to our existing iron ore concentrating
Nov 01, 2021 The most common method to concentrate apatite from carbonate phosphate ore is reverse configuration using fatty acids as collectors and inorganic acids as apatite depressants, such as H 2 SO 4 and H 3 PO 4.This work evaluates the process based on the separation between apatite and calcite by flotation, in bench and pilot scale, using carbon

Jun 01, 2021 The application of nanobubbles through flotation of coarse apatite tailings evidently improved the process' metallurgical responses compared to flotation by conventional bubbles only. The results indicated that nanobubble flotation of the as received apatite tailings −850 μm was an attractive option that can minimize the CO 2 footprint

process of preparing the low grade phosphate ore for obtaining the phosphate concentrate using the flotation concentration. The apatite concentrates are obtained using the selective flotation from the silicate and oxide minerals while defining the process of selective flotation of apatite from carbonate deposits is the major problem worldwide.
