| Abstract: | The depleting and diluting tendency of phosphate ore in several main ore districts in China are described, and some basic situations about rare earth and potassiumaccompanying with lower grade ore are mentioned here. So far many efforts for the challenge of the deficiency crisis have been made by chemical scientists and engineers at home and abroad.And the developments of study on the comprehensive utilization of lower grade phosphate rock, such as beneficiation, west-process leaching and thermo-process acid making,are stated.The suggestions for improving resource utilization efficiency and sustainable development are presented,which are involved with investigating on the secondary and lower grade ore, developing high level chemical products, comprehensively utilizing lower grade ore and readjusting policy. |
