Lateritic nickel minerals constitute about 80% of nickel reserves in the world, but their contribution for nickel production is about 40%. The obstacles in extraction of nickel from lateritic minerals are attributed to their very complex mineralogy and low nickel content. Hence, the existing metallurgical techniques are not techno-economically feasible and environmentally sustainable for processing of such complex deposits. At this juncture, microbial mineral processing could be a benevolent approach for processing of lateritic minerals in favor of nickel extraction. The microbial mineral processing route offers many advantages over conventional metallurgical methods as the process is operated under ambient conditions and requires low energy input; thus these processes are relatively simple and environment friendly. Microbial processing of the lateritic deposits still needs improvement to make it industrially viable. Microorganisms play the pivotal role in mineral bio-processing as they catalyze the extraction of metals from minerals. So it is inevitable to explore the physiological and bio-molecular mechanisms involved in this microbe-mineral interaction. The present article offers comprehensive information about the advances in microbial processes for extraction of nickel from laterites.

“…Leaching was performed on an orbital shaker for 24hrs with sulphuric acid at concentrations of 1 M, 0.5 M and 0.25 M and a 10:1 leaching ratio (cf. Esther et al, [9]). The extracts were filtered through 0.2 µm cellulose acetate filter and analysed by ICP-OES.…”

“…The metabolic mechanism of dissimilative iron reducing microbes (DIRM) has been widely exploited to reductively solubilise the ferric iron within these ores/wastes. This reductive dissolution can result in the release of any metals associated with the ferric (hydroxy)oxides to the aqueous phase, facilitating their extraction [3][4][5][6][7][8][9][10].…”

Abstract. Bioreduction of ferric iron-rich wastes is a rapidly emerging technology for the extraction/ recovery of metals from low-grade ores and metallurgical wastes. However, despite studies being successful, they have only been demonstrated at laboratory scale and issues relating to economic, industrial scale application have yet to be studied. Using bioreduction as a pre-treatment to increase recovery yield is a relatively new concept. This study examines the biostimulation of microbial communities to induce bioreduction of metalliferous sludge and the effect that this has on the leachability of metals from the waste using dilute sulphuric acid. Data shows an increase in both zinc and copper leachability after bioreduction, with maximum six fold and eleven fold increase (compared to pre-treatment) in the amount of zinc and copper leached respectively.

“…The numerous microbe-mineral interactions act as a link to understand the innate mechanisms of certain phenomena taking place in nature and assist to study the mineral surfaces and changes occurring in minerals with respect to time and action of microbial species (Mapelli et al 2012). Over the past few years, the interactions of selected microorganisms for beneficiation and bioleaching of the low-grade minerals/mineral wastes have been reported (Baba et al 2011;Erust et al 2013;Esther et al 2013;Panda et al 2012aPanda et al , b, 2013aPanda et al , 2015 and gradually gaining lot of importance for providing eco-friendly methods of environmental reclamation.…”
