Flotation Cells are used for Silica removal as underflow in first stage of flotation whereas Phosphates and Carbonates are extracted as froth In second stage additional bank of Flotation Cells are used to remove carbonate rejects as froth and Phosphate Concentrates as underflow which is then processed through cleaner flotation Cells before taking for thickener concentration and filtration
Sometimes the 18 mesh x 35 mesh ore is separated from the feed and either blended with the pebble ore sent to a coarse froth flotation circuit or chemically upgraded The 35 mesh material is sent to conditioning tanks where reagents are added prior to a series of froth flotation cells where the phosphate ore is recovered from the silica and remaining clays
