Separation of refractory rock phosphate (P2O5 = 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.

Ore Beneficiation - an overview ScienceDirect Topics

Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy source), iron oxide particles having higher phosphorous contents were seen to be colonized by different bacterial cells.

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.

Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.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.

Phosphate Rock - an overview ScienceDirect Topics

Production requires first the beneficiation of the ore, followed by acid leaching and separation. In general, the beneficiation stage does not result in a reduction of NORM in the ore. Treatment with sulfuric acid leads to the production of gypsum (phosphogypsum), which retains about 80% of Ra-226 and 30% of Th-232 and 14% of U-238.
