However, the low capacity of the electrostatic separators limits their use for large scale production.
Magnetic Separation This is the separation of minerals from other minerals or gangue by use of their differences in magnetic properties. E.g. separation of magnetic valuable mineral from non-magnetic gangue or vice versa. Magnetism arises from the spin of unpaired electrons in the 's' or 'd' orbits of atoms. Materials can be classified as; a) Diamagnetic – these are repelled along ...

1 The sources for this phosphate rock are either sedimentaryphosphorites(29–35wt%P 2O 5)origneousapatites ( 27 wt% P 2O 5), with the phosphorus occurring as apatite minerals (Ca 5(PO 4) 3(F, OH, Cl)). 2 The phosphate rock is converted to phosphoric acid (H 3PO 4) which is used to produce phosphate fertilizers. In the wet phosphoric acid ...
Mar 07, 2018· In particular, rock phosphate is an alkaline material that is used to reduce metal solubility by increasing soil pH and enhancing sorption of metal on its surface (Chen et al. 2007). Applications of natural rock phosphate to a multi-metal (Cd, Cu, Pb, and Zn) contaminated soil can reduce their solubility and increase sorption from solution ...

2.3. Electrostatic Separation Electrostatic separation is always used to pre-concentrate grained phosphate minerals by discarding a certain proportion of silica. This approach can reduce the energy consumption of grinding and the cost of chemical reagents and water usage. Sobhy and Tao investigated the
used to supply food and feed for mankind and animals. There is no substitute for phosphate rock as a raw material in the production of phosphatic fertilizers in the world at this time. As the world population continues to increase, so does the demand for phosphate. The low grade calcareous phosphate rocks have no direct use and
Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. Pure phosphorus is used to make chemicals for use in industry. The most important use of phosphate rock, though, is in the production of phosphate fertilizers for agriculture. Virtually all …
