Figure 1—Typical phosphate losses in Florida Great effort is spent by the phosphate industry to beneficiate the rock to obtain a concentrate containing 30%-31% P 2 O 5 During this process, much of the phosphate values are lost to the tailings stream
The bulk of the world's phosphate reserves is located in sedimentary horizons that contain appreciable amounts of carbonate During beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers This reject also mostly contains low tricalcium phosphate content and high carbonate content
A Tailor Made Approach for the Beneficiation of Phosphate Rock In parallel, beneficiation methods for phosphate rock are finite and include: comminution and size separation (crushing, grinding, attrition, screening and classification), mineral separation (flotation, gravity and magnetic separation) and ocassionally, stone ,
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 phosphat

Classification In Beneficiation Of Rock Phosphate classification in beneficiation of rock phosphate Method for beneficiation of phosphate rock A process is disclosed which removes gangue minerals from phosphate rock by forming an aqueous slurry of phosphate rock and its impurities, then using a low boiling
The enrichment of the low-grade-phosphate ore of the Tozeur-Nefta deposit was investigated using scrubbing-attrition, ball grinding and anionic/cationic reverse flotation in order to separate phosphate-rich particles from their gangue The choice of the beneficiation process was based on the petrographic, mineralogical and chemical analys
rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 55 and 72
Jan 27, 2014· Beneficiation of Phosphate Ore, by S Komar Kawara and JT Carlson, examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric ac The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate)
Beneficiation Washing and Classification The first product to be removed during hydraulic processing of the matrix is the pebble size fraction, -¾ in to +14 mesh The -14, +150 mesh particles are recovered by flotation Clay, sand and phosphate particles smaller than 150 ,
The chemical analysis of the rock revealed that P 2 O 5 = 251%, CaO = 527%, SiO 2 = 117% and CaO:P 2 O 5 ratio = 21 The main problem of this ore is its high content of calcite mineral The separation of such calcite gangue from apatite “phosphate mineral” is the main target of this beneficiation process
Phosphate Beneficiation Background Definition of “Beneficiation”: This is the second step in the mining process, after removal of the ore from the ground Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other
To concentrate phosphate rock in apatite (BPL or P2O5 content) we have to separate impurities from apatite using a beneficiation process The beneficiation process could include a large variety of operations depending on the rock impurities content, the particles size and their hardness
