Abstract EN
Solvent extraction (SX) separation of Al from Ni sulphate leach liquor (LL) of spent Raneynickel catalyst containing 0.12 M Al and 1.448 M Ni using organophosphorus extractants has been investigated.
Optimization of process conditions includes aqueous pH, extractant concentration, phase ratio, and stripping.
Comparison of Al extraction efficiency with 0.45 M extractant concentration for TOPS 99, PC 88 A, and Cyanex 272 at an equilibrium pH of 2.23 was 81.8%, 98.6%, and 75%, respectively.
The corresponding coextraction of Ni was 0.65, 0.6, and 0.9.
Among the three extractants screened, PC 88A showed better extraction efficiency for Al at lower pH values than the others.
Using 0.45 M PC 88 A, extraction isotherm was obtained at an aqueous-to-organic (A : O) phase ratio of 1 : 1–3 and O : A ratio of 1 : 1–5, which predicted possible separation of Al in 2 stages at A/O ratio of 2.
Quantitative stripping was achieved by H2SO4.
