2012-12-26 The dry process is a four-step process used to produce phosphoric acid industrially. We will take a look at the dry process to see how Thermodynamics can be used to answer practical problems encountered in real life. In the first step, a common mineral containing phosphorus and contaminated with silica is heated with coal in an electrical oven.

Phosphoric acid is one kind of colorless liquid with no odour. The production of phosphoric acid are mainly including there ways, wet process, the thermal process, and the dry kiln process. If use wet process, we will get low-concentration phosphoric acid, with much more impurity, therefore, it should have another purification of phosphoric acid.
