In the Kiruna-type iron ores, apatite has been regarded as the most conspicuous mineral. Advocates of the magmatic-intrusive mode of ore emplacement at Kiruna have argued that the apatite crystallized from a parent ore magma. However, a closer examination of deposits classified as Kiruna-type ores shows that they include both apatite-bearing and virtually apatite

Phosphorite Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation. By comparison, the average phosphorus content of sedimentary rocks is less than 0.2%. The phosphate
