The Versatile Apatite Mineral Group - Advancing Mining

20/05/2014  The largest apatite deposits are found in sedimentary rocks, but apatite also occurs in igneous and metamorphic rock. In sedimentary beds of phosphate rock, apatite occurs as a white or brownish earthy mass which must be detected by chemical tests. Because there is such a large range in composition of the various apatites, eight elements must be monitored (P, Al, Si, Na, K, Ca, Fe and Ti)

LKAB produces Apatite from mine waste in a new pilot plant

Here, the apatite will be processed into phosphorus mineral fertilisers, rare earth elements, fluorine and gypsum. Phosphorus and REEs are listed by the EU as Critical Raw Materials due to their high economic importance and our import dependence. But right now, Leif Boström is pleased to be able to inform of the successes with the apatite production that is the needed first step.

Apatite: From Crystals to Phosphate Rock Rock Gem

High-grade phosphate rock, the only commercial source of phosphorus, contains at least 10 percent elemental phosphorus in the form of apatite. As the base of the 25-billion-dollar-per-year global mining industry, more than 255 million tonnes of phosphate rock are mined annually from open pits. After concentration, an acid treatment converts the apatite into a hydrated calcium phosphate
