Structural and spectral studies on gypsum crystals under simulated conditions of phosphoric acid production with and without organic and inorganic additives

In the dihydrate process to produce phosphoric acid, phosphate ore [Ca10F2(PO4)6] is leached with sulfuric and weak phosphoric acids to produce phosphoric acid and gypsum as a by-product. Crystallization of gypsum occurs as the leaching is taking place. The effect of organic and inorganic additives...
