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. Thisprocess has been abandoned because of the amount of energy which is needed. Theprocesses that use phosphated minerals which are decomposed with an acid, are known as"wet processes" and they are the only economic alternative way to produce phosphoricacid.
