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 …

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
