Phosphorite

Froth flotation is used to concentrate the mined phosphorus to rock phosphate. The mined ore slurry is treated with fatty acids to cause calcium phosphate to become hydrophobic . For general use in the fertilizer industry, phosphate rock or its concentrates preferably have levels of 30% phosphorus pentoxide (P 2 O 5 ), reasonable amounts of calcium carbonate (5%), and lt;4% combined iron and aluminium
