World phosphorous pentoxide (P 2 O 5) production capacity is about 50 million tonnes per year according to PhosEnergy 9.5 Mt in North America 9.4 Mt in Africa and 19.2 Mt in Asia. About 20 of US uranium came from central Florida s phosphate deposits to the mid

Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium lead nickel copper chromium and uranium. Unless carefully managed these waste products can leach heavy metals into groundwater or nearby estuaries.

Nov 11 2013 · In the sphere of environmental opposition to mining phosphorite has been noteable on account of the "Phosphorite War". This is the name given to a late-1980s campaign in the then-Estonian Soviet Socialist Republic against the opening large phosphorite mines in the Virumaa region.

Phosphorite phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly from 4 to 20 phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28 often more than
