Rock Phosphate Impurities And The Impact On Manufacturing

21-06-2012Rock phosphate demand worldwide for manufacturing phosphoric acid is growing exponentially. The availability of good quality rock phosphate is limited. Till the end of last century rock phosphate quality was good and little attention was given to the effect of impurities associated with these rocks. With limited resource of good quality rock phosphate now phosphoric acid industry is forced

Dicalcium phosphate is commonly produced through the "wet acid" route in which rock phosphate is reacted with sulphuric acid to produce phosphoric acid. After concentration and purification (to reduce the level of impurities), phosphoric acid is reacted with a calcium source (commonly quick lime or limestone) to produce dicalcium phosphate.

In ball mill 6, the phosphate rock is ground in a medium of fresh water so that the ground rock will pass a screen of selected mesh, e.g 30 mesh. Fresh water is introduced into the ball mill 6 via a fresh water recycle line 10 and a fresh water make-up line 12.

Phosphorite, or phosphate rock, is the most significant secondary rare-earth resource. It contains high amounts of phosphate-bearing minerals along with low contents of rare earth elements (REEs). In Florida, about 19 Mt of phosphate rock are mined annually and most are used to manufacture fertilizers using a wet process, in which sulfuric acid reacts with phosphates to produce phosphoric acid

Wet-process sulfuric acid acidulation is the most common technique for treating phosphate rock. Phosphoric acid is produced by the reaction of sulfuric acid with phosphate rock. Phosphoric acid, also known as orthophosphoric acid, is very often further concentrated by evaporating water and formation of superphosphoric acid.
