Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted.

Phosphate Products. Phosphate is the workhorse of all minerals in the plant world. An important role that phosphate plays is the translocation or movement of minerals into the plant. Phosphate is also responsible for improved seed germination, improved root development and is foundational for photosynthesis.

The WAPHCO Project consists of the construction of a phosphoric acid plant producing 500,000 metric tons of P2O5 per year as merchant grade acid ("MGA") from the adjacent Abu Tartour phosphate ore mine in the southwestern desert of Egypt. The main issue with that ore is the high content of minor elements like iron, aluminum and …

The Work Index is actually the total work input in kwhr/short ton required to reduce from theoretically infinite particle size to 80% passing 100 microns, or to approximately 67% passing 200 mesh. Knowing the Work Index, one has but to apply the proper given equation to determine the power input required.
