Mining and Beneficiation – Phosphate Research Network

The concentrations of phosphate ores deposits are going to be low and phosphate ore beneficiation is becoming a real challenge for phosphate industry. The froth flotation could be considered up to now as a good solution but it consumes a lot of water and chemical reagents and leads to huge quantities of sludge (tailings). The R&D should explore ...

Review on Beneficiation Techniques and Reagents Used for ...

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.
