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.
Blue Apatite Goddess Crystals. Blue Apatite honors Gaia, the Greek Earth Mother Goddess. Born directly out of Chaos, the primal emptiness, she was the first (or one of the first) beings to appear during the process of creation, and is honored as being the Earth itself.
Dec 21, 2011· To keep mining practices from permanently destroying wildlife habitat, all states including Florida, where most phosphate rock is mined, require the reclamation of mining areas. The two stages of reclamation are contouring and revegetation. Contouring is the stage in which the mined land is reshaped to resemble premining topography and drainage.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material.
