How much grade of phosphate rock is needed for industrial-grade phosphoric acid.
Phosphoric acid is the basic raw material for the preparation of various industrial and agricultural phosphorus products, and the production process of phosphoric acid at home and abroad mainly includes "thermal method" Phosphoric acid is a common raw material used in the manufacture of phosphate fertilizers, pesticides and pharmaceuticals in industry. At home and abroad, due to the complex process, high production cost, and large amount of wastewater discharge, a large amount of phosphate is discharged into the environment and causes serious pollution, so it is necessary to treat phosphoric acid to reduce resource waste and achieve the goal of double harvest of economic and social benefits.
At present, the domestic production of sodium phosphate generally adopts the ion exchange method, the main principle of which is to convert the metal hydroxide (or sulfide) in the solution into non-volatile divalent iron ions (FeSO4) in the electrolyzer to obtain calcium phosphate; Potassium phosphate can also be used as organic fertilizer, which requires a large amount of ore and a small amount of water.
Phosphate rock produces phosphoric acid.
The methods of producing phosphoric acid from phosphate rock include: using oxidants to chemically react phosphate rock to produce calcium phosphate. Calcium phosphate is obtained as a white crystal at room temperature. Its main components are calcium phosphate (PB) and ferrous salt (Ca2+), which can be used as raw materials or chemical products for fertilizers, building materials and metal materials.
Calcium phosphate is an inorganic compound, also known as yellow-green precipitate, which is the main raw material for the treatment of insoluble organic wastewater, and is widely used in petroleum exploitation, metallurgy and other sectors.
