Extraction from extracting nickel laterite nickel ore handling process

by:Deyuan      2020-08-13
Laterite nickel ore is a raw material for extracting common metal nickel laterite in jinchuan nickel mine extraction metal nickel is developing very quickly. Laterite nickel ore are mainly distributed in line within 30 degrees north and south of the equator tropical countries, while China's nickel ore reserves 70% concentrated in gansu province, the second distribution in xinjiang, yunnan and hubei, jilin, sichuan, shaanxi and qinghai 7 provinces, the total reserves accounted for 27% of the total reserves of nickel resources in the nation.

laterite nickel ore extraction method of metal nickel:

for nickel laterite nickel ore extraction solvent extraction method is adopted to improve the operation. Solvent extraction is a liquid liquid extraction, extraction by organic phase and water phase are mixed, water phase to separate the material into the organic phase, again by two phase mass density different separate two phase.

nickel laterite nickel ore extraction process:

after nickel ore mining needs will be broken ore first, and then by solvent leaching, leaching liquid to adjust PH value, and then select the suitable extractant, extraction equipment according to capacity of model selection, generally choose CWL650 - M type centrifugal extraction machine. Prophase work when ready, will leach liquor and extraction agent according to certain proportion respectively from different entrance into centrifugal extraction machine, with the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer process. Mixture again after the effect of drum centrifugal force through two separate out of the body side by side. Organic phase after extraction, into the subsequent section crystallization purification, made into finished products.

nickel extraction operation flow chart:



centrifugal extraction machine is widely applied in many fields of extraction section, because it works with the traditional extraction equipment, centrifugal extraction machine is the use of motor driven rotary drum high-speed rotation, the density of different and each of two immiscible liquids in drum or under the action of shear force produced by the rotation of blades complete mixing and mass transfer, and the effects of the centrifugal force in the high-speed rotating drum under rapid separation.
