· Consequently, rocks containing a large amount of CO2 are more affected. (Becker, 1989) The process of mining and beneficiation to produce one ton of commercial rock phosphate (32 % P2O5) requires approximately GJ/tonne rock or GJ/tonne P2O5. If the rock is calcined the total energy requirement is doubled (Ullmann, vol.

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.
