  • Chemical Processing of Phosphate - Florida Poly

    Chemical Processing of Phosphate The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It

  • 11.21 Phosphate Rock Processing - US EPA

    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; allwet grinding

  • Phosphate Rock Plants: New Source Performance

    Aug 03, 2020  The 6-digit Source Classification Code (SCC) for phosphate rock processing is 3-05-019.

  • Radioactive Material From Fertilizer Production US EPA

    Jun 02, 2021  Phosphate rock contains the mineral phosphorus, an ingredient used in some fertilizers to help plants grow strong roots. Phosphate rock contains small amounts of naturally-occurring radionuclides, mostly uranium and radium. When processing phosphate rock to make fertilizer, the phosphorous is removed by dissolving the rock in an acidic solution.

The particle size of the acid mist ranges from l.4 to 2.6 micrometers. It is

  • Reclamation of Phosphate-Mined Lands

    Chemical processing is necessary because phosphate rock is not watersoluble. Approximately five tons of phosphogypsum are produced for every ton of phosphoric acid produced. This processing by-product must be stockpiled in stacks per a 1989 EPA rule that banned its use because of the trace amounts of radioactivity in the substance.
