A Review on Solvent Extraction of Nickel - IJERT

2019-7-1  The alkylphosphinic acids are most widely used for extraction and separation of nickel. Most of the work reported is related with Cyanex 272 as it has been proven an efficient extractant with faster kinetics and higher loading capacities. Separation using CYANEX 272 is achieved mainly by the control of pH. The main problem associated with CYANEX 272 is it requires high amount of alkali to maintain pH. CYANEX 301 and CYANEX 302 both extract nickel

A Review on Solvent Extraction of Nickel – IJERT

2014-9-30  Primarily nickel can be obtained from leaching of nickel laterite ores and sulfide ores [5-6]. The leach liquors obtained by leaching of ores contains significant amount of nickel along with copper and other metallic impurities. Laterite ores contains about 0.5-1.5% nickel [5] and sulfide ores contains about 0.3-1% nickel.

EXTRACTION OF NICKEL FROM A MIXED NICKEL

2019-3-2  High pressure acid leaching (HPAL) technique is currently used by Meta Nickel, Gordes/Turkey to extract nickel and cobalt from lateritic nickel ore. PLS is fed to first partial neutralisation unit to re-move impurities such as iron, aluminium, chro-mium by increasing pH of the leach solution up to ~3.3. The neutralised leach solution is send to second neutralisation unit to achieve com-plete rejection of the impurities by increasing pH of the leach solution from ~3.3 to ~5.5 and then the leach solution is precipitated by using MgO to obtain MHP product. The MHP product de-pending on PLS consists of ~34-38%Ni and ~1.8-2.1%Co along with other impurities such as man-ganese, magnesium and calcium. In the present study, the main objective was to investigate the extraction of nickel
