Wet Process Phosphoric Acid Plants In the wet process phosphoric acid plant, the raw materials are ground phosphate rock, 93 percent sulfuric acid, and water. Phosphate rock is mixed with the sulfuric acid after the acid has been diluted with water. This reaction produces phosphoric acid and gypsum.

Phosphate beneficiation plant In the treatment of phosphatic shales for recovery of phosphate, a simple low cost flexible flowsheet is highly desirable. Since all grades of ore from low to high P2O5 content may occur in a deposit it is important to consider the possibility of either mixing the ores or to segregate them into grades for separate treatment.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the lowgrade phosphate ore is, hence, of great necessity.
