11.21 Phosphate Rock Processing - US EPA

2015-9-10  The major emission sources for phosphate rock processing are dryers, calciners, and grinders.These sources emit particulate matter (PM) in the form of fine rock dust and sulfur dioxide (SO2).Beneficiation has no significant emission potential because the operations involve slurries of rock andwater. The majority of mining operations in Florida handle only the beneficiation step at the mine;

Processing Phosphates for Use in the Fertilizer Industry

Phosphate rock can be processed into a variety of phosphatic fertilizers. Most commonly, it is processed into Monoammonium Phosphate and Diammonium Phosphate fertilizers, also commonly known as MAP and DAP. MAP DAP Fertilizer Production Once phosphate rock has been mined, the actual phosphate ore is beneficiated to separate it from the unwanted materials. This is carried out via a wet process,

How phosphate is mined and processed

2014-4-21  Processing 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. Sulfuric acid production creates a lot of heat. This heat is used by a power plant to generate electricity, which helps to power both sulfuric acid production and phosphoric

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.
