Phosphate Mining - Center for Biological Diversity

Most mining of phosphate rock involves clearing large swaths of vegetation and digging up the soil beneath to reach the phosphate-ore-containing matrix 60 to 80 feet below the surface. This matrix is then transported by pipeline to a nearby plant, where the phosphate ore is forcibly separated from the sand and clay by a process known as ...

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.
