Among the deleterious impurities in phosphate rock, dolomite is the most troublesome. Dolomite causes higher consumption of sulfuric acid, reduces filtration capacity, and lowers P 2O 5 recovery in the fertilizer manufacture process. Almost 50% of the future phosphate reserve in Florida are contaminated by dolomite. In 1994, FIPR conducted

efficiency is even more critical. Unfortunately, process control in phosphate beneficiation plants is still primitive, after 100 years. This is due to the following difficulties in analyzing the plant slurry: (1) multi-element analysis is required for meaningful process control (P,O,, CaO, SiO 2, and MgO), (2) the slurry is a

Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore. In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the phosphate rock concentrate is utilized to produce …

At the beneficiation plant the phosphate is separated from the sand and clay. After going through beneficiation, the clay slurry is pumped to a settling pond. The sand is sent back to the mine site to be used in reclamation and the phosphate is sent to the chemical processing plant where it is processed for use in fertilizer and other products.

Phosphorus in rock is pretty insoluble and thus not directly available to plants. In nature, rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants.
