  • Chemical Beneficiation of Phosphate Rock E & MJ

    Uranium, Rare Earths, Radium, FluorineProduction of Dicalcium PhosphateUsing Phosphoric AcidSummaryReferencesDilute nitric acid [20%] or dilute hydrochloric acid [10%] can be used to one’s advantage for leaching phosphate rock. This permits the use of standard hydrometallurgical processes such as in situ, vat and heap leaching. The reaction is rapid and does not need agitated reactors. Nitric or hydrochloric acids used in the process are recycled and recovered. Makeup acid is added to compensate for that consumed to react with impurities. If phosphoric acid is needed, then the leach solution must be treated with HNO

    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.This occurs through washing, screening

  • 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.
