PHOSPHATE ROCK
Phosphate rock is obtained from geological deposits. Its primary constituent is apatite, a calcium phosphate mineral. Phosphate rock is the basis material for almost all phosphate fertilizers, either as such or transformed into phosphoric acid. When added to the soil, phosphate rock slowly dissolves and gradually releases its nutrients.

Uranium from Phosphates
When phosphate rock is treated with sulphuric acid in sub stoichiometric quantity, normal superphosphate is formed. If more sulphuric acid is added, a mixture of phosphoric acid and gypsum (calcium sulphate) is obtained. After the gypsum is filtered out, the resultant phosphoric acid can be treated to recover uranium. The basic reaction is:
