Novel approach for enriching nickel content in lean

Novel approach for enriching nickel content in lean

May 01, 1996 In this paper, a process for enriching the nickel content of the lateritic nickel-bearing chromite overburden, normally a waste material generated during chromite mining, is described. In this flotation process, a nickel preconcentrate containing 1.1% Ni was obtained from material containing as little as 0.36% nickel.

Bioleaching of nickel by Aspergillus humicola SKP102

Bioleaching of nickel by Aspergillus humicola SKP102

Jan 01, 2016 This chromite mining overburden contains nickel, the only source of the metal in the country. During this study Aspergillus humicola SKP102, an indigenous fungus isolated from the mining overburden was employed for the leaching of nickel. About 53.89% of the nickel could be leached by the fungus when grown in batch mode using a Czapek dox medium containing 2% (w/v) of the mining overburden.
