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

How phosphate is mined and processed

2014-4-21  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.

What Is Involved in Phosphate Mining? (with pictures)

2021-2-11  Phosphate mining is an important part of the process of producing chemical fertilizers. The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are located. Most phosphate mining is conducted as open-pit mining rather than subsurface mining.

Difference Between Phosphorus and Phosphate

2011-7-19  The phosphorus cycle is a biogeochemical cycle, which describes how different forms of phosphorus circulate within the earth. It is mainly restricted to the lithosphere, because phosphorus doesn’t have a gaseous phase. Phosphorus is largely found as phosphates, stored in soil, fossils, animal and plant bodies and in water systems.
