phosphate mining apatite

Apatite: Mineral information, data and localities.

"Apatite" is a field term for unidentified calcium phosphate members of the apatite group. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. "Apatite" crystals are short to long hexagonal prisms [0001], with {10 1 0} and {10 1 1} dominant; also thick tabular {0001}, frequently in the crystals of hydrothermal origin in pegmatites and ...

Use of phosphate rocks for sustainable agriculture

Phosphate is the component of agronomic interest in these rocks. The higher the phosphate (P 2 O 5) content as apatite, the greater the economic potential of the rock. Factors that are important in the chemical conversion of PRs to fertilizer (free carbonates, iron (Fe), aluminium (Al), magnesium (Mg) and chloride) are often not important where ...

Acid Alcohol Leaching of Apatite - 911metallurgist.com

Typical processing involves mining the ore and beneficiating through sizing and flotation to produce a "phosphate rock" concentrate containing over 29 pct P2O5. This concentrate is ground to 90 pct minus 75 µm and leached to dissolve the phosphate. Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock.
