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 (concentrate) and a waste stream . Examples of beneficiation processes include froth flotation and gravity separation.
Phosphate rock grades are decreasing worldwide as the richer deposits are mined out. While there is plenty of low grade phosphate rock in the world which can be recovered it is becoming more expensive to produce good grade rock for easy processing into phosphoric acid and other fertilizer products.

The discussion part was mainly concerned on the environmental impact of phosphate mining and processing
Worldwide, most soils and crops require phosphorus (P) additions to improve fertility and production. Directly applying unprocessed phosphate rock to soil may provide a valuable source of plant nutrients in specific conditions, but growers must consider several complicating factors and limitations.
The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P 2 O 5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates.

Oct 11, 2017· The cost curves presented below are a collation of sites with collected cadmium deposit data, imposed onto the 2021 phosphate rock cost curve. The curves do not account for any cadmium removal within beneficiation or the phosphoric acid process.
Phosphate fertilizers are prepared by beneficiation of phosphate rock to remove its impurities, followed by drying and grinding. The PO 4 in the rock may then be reacted with sulfuric acid to produce normal superphosphate fertilizer. Over 100 plants operating in the United States produce approximately a billion kilograms of phosphate fertilizer ...
Beneficiation: 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.
