Oct 06, 2018· By virtue of its chemical behavior, apatite is generally associated with fluoride, which is a potential risk for human health. During the current decade there is a rising concerns about the environmental impacts of the phosphate mining industries.
Phosphorus is common within geological materials. The average continental crust contains % P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorousbased products. 2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores.
"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 ...
