What Is Involved in Phosphate Mining? (with pictures)

Apr 30, 2020  Phosphate mining involves the extraction of ores containing chemical compounds rich in substances that contain the phosphate ion. These ores vary in their composition, and different varieties of phosphate rock require different mining techniques. Processing of the mined ore follows extraction. Finally, mining sites are rehabilitated to minimize ...
