Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities In order to obtain a qualified phosphate concentrate the beneficiation of the low grade phosphate ore is hence of great necessity

Many beneficiation techniques can be employed to upgrade the P 2 O 5 grade of phosphate ores based on their characteristics in chemical composition and texture The flotation process is most widely applied to balance the P 2 O 5 recovery ratio and cost In this review the dominant techniques for the beneficiation of phosphate ores are introduced
