phosphate by calcination and flotation

Phosphorite - Wikipedia

The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5. This occurs through washing, screening, de-, magnetic separation or flotation.

Abstract. Separation of refractory rock phosphate (P 2 O 5 = 11.5%) from the Dalir area, Iran, containing quartz, calcite and other impurities, by calcination and flotation processes has been successfully used to upgrade the phosphate values. Petrographic studies of this ore showed that collophanite was the major phosphate mineral and the main gangue minerals were calcite, dolomite and quartz.
