Mechanical activation of the phosphate rock

2009-8-9 · World processed phosphate trade has increased substantially. Total exports of phosphoric acid, ammonium phosphate and triple superphosphate increased from an average of 8 Mt P2O5 between 1984 and 1986 to 15 Mt P2O5 in 1998, despite a fall in total phosphate consumption during this period. Today, ammonium phosphate accounts for approximately

Our Technology

Uses low quality rock. Consumes low-quality rock with high silica and other impurities. P2O5 as low as 10-15% vs ~30% for wet-acid process. Impurities, e.g. iron, aluminum and magnesium can be much higher than for wet-acid process. No need for expensive beneficiation steps, like flotation: can unlock value of uneconomic reserves.

PHOSPHORIC ACID PLANT

Phosphate preparation unit consists of 3 main processes: crushing, grinding and thickening. The raw phosphate rock is (19-20% P2O5) crushing to the desired sizing. Sized phosphate is grinding in a OUTOTEC AG Mill, and then elected by special sieves. It's obtained concentrated phosphate (24-26% P2O5).
