11.21 Phosphate Rock Processing US EPA

Phosphate rock mined in North Carolina does not contain pebble rock. In processing this typeof phosphate, 10-mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh istreated by 2-stage flotation, and the fraction larger than 10 mesh is used for secondary road building.

How phosphate is mined and processed

The phosphate is sent to a chemical processing plant, or fertilizer manufacturing plant. Here, molten sulfur, shipped to Florida ports and trucked to the plant, is used to create sulfuric acid. The sulfuric acid is then mixed with the phosphate to make phosphoric acid. The phosphoric acid is the main ingredient in fertilizer, but can also be used in animal feed supplements, soda, or soap.
