Grinding of rock phosphate and its impact on optimisation ...

In production of phosphoric acid, primary purpose of rock phosphate comminution is to expose or create sufficient porous surface area to allow complete dissolution of the rock in relatively short duration at the conditions of acid strengths and temperature prevailing in reactor or attack tanks. Secondary purpose is to reduce power input to agitators in the attack circuits.

Investigation on pre-weakening and crushing of

2014-11-1  Phosphate ore was chosen because its comminution inherently produces a high level of slime which disrupts the downstream processes and reduces the quality of the final product. In this study, a high voltage electrical pulses unit was designed, developed and tested to investigate the effect of the instrumental parameters on failure and ...

Lessons in Sustainability from the Mining Industry ...

2014-1-1  The traded rock phosphate is only 16% of the total rock phosphate produced [6], indicating the high degree of vertical integration in the industry. This is similar to the alumina industry and means that any shortages of supply or increases in demand result in an exaggerated swing in prices until new capacity is installed.

Phosphate Rock Properties

2021-2-18  Defluorinated and Fused Phosphate Rock. Defluorinated phosphates are obtained by calcining or fusing phosphate rock with silica and/or phosphoric acid in the presence of water vapor. At temperatures ranging from 1,400° to 1,600° C., the bulk of the fluorine is evolved, and the P2O5 is rendered citrate soluble.
