Ambient Temperature Flotation of Sedimentary Phosphate Ore

Froth flotation is considered as the most effective process for the beneficiation of the sedimentary phosphate ore, due to the high efficiency of removing silicate and carbonate gangue minerals [4,5].Reverse flotation is effective and is usually applied to remove carbonate gangues from phosphate ores with sulfuric acid, with phosphoric acid being used as a pH regulator and depressant [6,7].
