Rock Phosphate

Dec 13, 2016· Other benefits to the direct use of rock phosphate are: 1 It is relatively cheap compared to inorganic/chemical phosphorus fertilizers 2 It is environmentally friendly As a natural source of phosphorus, it avoids the use of inorganic fertilizers which contribute to green house gas emission during its manufacturing process 3...

Phosphorite

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate mineralsThe 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 5This occurs through washing, screening ....

Phosphate Flotation

For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced...

Phosphoric acid

Apr 06, 2017· Some grades of commercial rock do not need grinding, their particle size distribution being acceptable for a dihydrate reaction section (60-70% less then 150µm) Most other phosphate rocks need particle size reduction, generally by ball or rod mills Both mills can operate with wet or dry rock CHEMICAL PROCESS INDUSTRIES...

Phosphate Fertilizer

The next step in the phosphate fertiliser production chain is the chemical treatment, which may contaminate the environment in the vicinity of the plant (Kucera et al, 2007; othman and Al-Masri, 2007) Wet-process sulfuric acid acidulation is the most common technique for treating phosphate rock...

Rock phosphate

Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means "change in form" The protolith is subjected to heat and pressure (temperatures greater than 150 to 200 °C and pressures of 1500 bars[1]) causing profound physical and/or chemical change...
