The beneficiation plant makes use of about 85% of the total volume of process water used in phosphate rock production. Phosphate rocks from crushing and screening, which contain about 60% tricalcium phosphate, are fed into the beneficiation plant for upgrading by rejection of the larger than 4 mm over-size particles.

Phosphate rock grinding mill Phosphate rocks are those minerals that contain the tetrahedral coordinated phosphate anion along with the freely substituting arsenate and vanadate. Chlorine, fluorine, and hydroxide anions also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.

A method is disclosed for the manufacture of phosphoric acid directly from phosphate rock wherein the crushed phosphate rock is mixed with dilute phosphoric acid to form a slurry and the slurry is then heated to produce calcium monophosphate. Thereafter, oxalic acid is added to the slurry to precipitate the calcium therein as calcium oxalate which is separated.
