Naturally occurring mineral products having sufficient phosphate content to be of commercial value are classified as phosphate rock. The grade or phosphate content of these products has been traditionally reported as percent Ca 3 (PO 4) 2, which is referred to as bone phosphate of lime (BPL), tricalcium phosphate (TCP), or triphosphate of …
Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs ...
In the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P 2 O 5 × 2.1853 = BPL). The latter term is reminiscent of the time when bones were the principal source of phosphate in the fertilizer industry.
