Phosphoric acid description, application and process ...

There are two ways in which phosphoric acid can be produced. The first is the wet process, where a phosphate-containing mineral such as calcium hydroxyapatite is treated with sulfuric acid. This produces phosphoric acid along with calcium sulphate precipitate. The second approach is called thermal process. Pure phosphorus reacts with air to ...

Phosphoric acid – Manufacturing process for Phosphoric acid

Phosphoric acid (H3PO4) can be produced by 3 main commercial methods: wet process, thermal process and dry kiln process. Wet process is by far the most common route and the acid can be used in phosphate fertilizers production (DAP, MAP, SPA). Thermal process phosphoric acid is of a much higher purity and is used in the manufacture of high grade chemicals, pharmaceuticals, detergents,

Booklet No. 4 of 8: PRODUCTION OF PHOSPHORIC ACID

Processes with different raw materials are used in the manufacture of phosphoric acid. The process is known as “thermal” when the raw material is elemental phosphorus. This process has been abandoned because of the amount of energy which is needed. The processes that use phosphated minerals which are decomposed with an acid, are known as “wet processes” and they are the only economic ...

A Clean Technology Phosphoric Acid Process – International ...

Phosphoric acid for use in fertiliser applications is mainly produced by a ‘wet process’, i.e. by digestion of phosphate ore with sulphuric acid. In such wet-processes, however, impurities like Cd and Ra, originating from the phosphate ore, are distributed between the phosphoric acid and the by-product, a calcium sulphate modification. The use or disposal of the by-product and probably the ...
