Rock phosphate contains

  • Solution

    Rock Phosphate It is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. The phosphate content of phosphorite is atleast 15 to 20% which is a large enrichment over the typical sedimentary rock content of, then 0.2%. The phosphate is present as fluorapatite Ca5 (PO4)3 F (CFA) typically in cryptocrystaline masses referred to as callophane.
