Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock. During leaching the apatite is solubilized as H3PO4 and the calcium content of the apatite is precipitated as calcium sulfate. In addition, any impurities in the ore are usually solubilized; the most common impurities are iron, aluminum, and magnesium.
