Rock phosphate grades are quoted as percent P2O3 or as percent TPL or percent BPL (Tri-Phosphate of Lime or Bone Phosphate of Lime, equivalent to 2.185 x percent P2O5). Sales of phosphate rock are generally by annual contract with consumers, with minimum grades about 30% P2O5 (about 66% TPL). This means that a 6% P2O5 phosphate rock will need to

ground phosphate rock with 65 to 75% sulfuric acid (virgin acid is preferred) (Mann 1992). The quality of phosphate rock is generally identified by its content of tricalcium phosphate (Ca3P2O8), called bone phosphate of lime (BPL). Chemical analyses are usually reported as the P2O5 percent (phosphoric acid) or percent of BPL (1% BPL = 0.485% P2O5).

bone-phosphate - definition and meaning

In the commonest form, popularly called bone-phosphate, which is the form in which lime and phosphoric acid are combined in bones, guano, and the ordinary mineral phosphates, the lime and phosphoric acid are combined in the form of what is known as tribasic phosphate of lime, or tricalcic phosphate -- that is to say, for every equivalent of phosphoric acid there are three equivalents of lime.
