Chemical and morphological modifications in apatite identified in this work can be related to detrimental effects on flotation recovery. For instance, the reddish apatite was fractured, and some grains show no CL, probably as a result of quenching caused by iron entering the apatite structure, which has also changed its color.

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.
