Over 80 pct of domestic phosphate rock, which is the starting material for phosphorus-containing fertilizers, comes from central Florida deposits. As higher grade deposits are depleted, lower grade phosphate ores containing mgo in the form of dolomite are encountered. Treating high-mgo ores with present beneficiation technology will not yield a concentrate meeting specifications for acidulation.

Mechano-milling is a process where materials are ball-milled at high energy to induce chemical and physical reactions. This study investigated the effect of milling on the properties and agronomic effectiveness of six apatite rock phosphates (RP). The effects of milling were evaluated by X-ray diffraction, BET-N2 surface area measurements, electron microscopy and solubility in 2% citric acid ...
Figure 6—Proposed process for the treatment of phosphate rock. using dilute nitric acid and hydrometallurgical techniques. The acid vapors can be condensed or washed with water for recycle. The residue, which typically analyzes 40% P 2 O 5, is insoluble in water but soluble in citric acid and can be marketed as a fertilizer or as a high-grade ...
The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. Breaks down under acid soil conditions to release phosphate to the soil over time. This research has already proven that Bayovar Rock Phosphate can help to increase oil palm yield by up to 2.6 mt more than medium reactive rock phosphate source.

The major emission sources for phosphate rock processing are dryers, calciners, and grinders.These sources emit particulate matter (PM) in the form of fine rock dust and sulfur dioxide (SO2).Beneficiation has no significant emission potential because the operations involve slurries of rock andwater. The majority of mining operations in Florida handle only the beneficiation step at the mine; allwet grinding …
