Phosphate rock comes from geologic deposits located around the world. Its main constituent is apatite, a calcium phosphate mineral primarily extracted from sedimentary marine deposits, with a small amount obtained from igneous sources. Most phosphate rock is recovered through surface mining, although some is extracted from underground mines.

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 and

Phosphate rock mining began in the Western United States in 1907 and in North Carolina in 1966. Phosphate rock production capacity doubled from 1960 to 1970 in response to increased demand for fertilizer and the shift to multinutrient, highanalysis fertilizers. Throughout the 20th century, fertilizer production was the major use of phosphate rock.
