mineral processing process of phosphate rock

Flotation process of Phosphate rock_MECRU

Phosphate rock is a kind of mineral containing oxygen rock and has high industrial utilization value. It is particularly widely used in ceramics, agriculture, food, fuel and other fields. With the increase of mining power, phosphate rock resources are becoming less and less, so We need to take certain measures to process and use phosphate rock.

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

How phosphate is mined and processed

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
