PRODUCTION OF PHOSPHORIC ACID - Product

2014-10-28  processes 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 phosphoric acid. There are three possible subgroups of wet processes depending on the acid that is used for the acidulation.

Chemical Production phosphoricacid

The Chemical Production of Phosphoric Acid. Phosphoric acid is needed in large quantities to be able to fill its many roles in industry, meaning that its production has to equal its large demand. This acid is most commonly created by two ways, with one being more energy intensive and more pure, while the other is faster and cheaper.
