phosphoric acid production process

There are two ways in which phosphoric acid can be produced. The first is the wet process, where a phosphatecontaining 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.
