Earlier the original source of phosphorus (P) fertilizer was bones; as time passes, the supply of P fertilizer will get exhausted. Today, rock phosphate is the only raw material in the form of P fertilizers. There are two types of rock phosphates: igneous and sedimentary; both have the same phosphate mineral, i.e., calcium phosphate of …
Bauxite: as petrographic term is a residual sedimentary rock product of tropical chemical weathering in which the free aluminium bearing minerals (alumina …
While the descriptions of processes used to produce various phosphate products seem fairly straight forward, efficient operation of a modern phosphate complex depends on careful management of impurities carried to the phosphoric acid from the phosphate rock and using acid of varying impurity levels for specific phosphate …
