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 …
Looking to the scarce rock phosphate resources in India, RSMML has put continuous effort for utilization of its low grade ore resources, which are abundant at Jhamarkotra but require beneficiation before its utilization by fertiliser industries as raw material. ... point of view RSMML has put up a beneficiation plant for processing of 9 Lacs MT ...
Apatite is the most common phosphate mineral and a vital nonrenewable resource which is the only economically feasible source of phosphorus for phosphate fertilizers and chemicals.
The Society for Mining, Metallurgy & Exploration (SME) has announced the availability of Beneficiation of Phosphate Ore. This new publication examines various methods for processing phosphate rock. Phosphoric acid has a wide variety of uses such as the production of fertilisers, pharmaceuticals and detergents.

Phosphate rock normally is used as a dry rock or in slurry form. However, in some cases, particularly where the raw phosphate is high in carbonaceous matter or it is desirable to have a clean acid, the rock is calcined. Also, in a few cases, the phosphate rock is calcined, the product slaked, and free lime separated as a beneficiation step.
Zn contribute to post-precipitation of insoluble phosphate. Other elements such as Cd, Pb, Cr, As, Hg, Se and V are either toxic or harmful in agricultural products.
