This review has as its underlying premise the need to become proficient in delivering a suite of element or metal products from polymetallic ores to avoid the predicted exhaustion of key metals in demand in technological societies. Many technologies, proven or still to be developed, will assist in meeting the demands of the next generation for trace and rare metals, potentially including the broader application of biohydrometallurgy for the extraction of multiple metals from low-grade and complex ores. Developed biotechnologies that could be applied are briefly reviewed and some of the difficulties to be overcome highlighted. Examples of the bioleaching of polymetallic mineral resources using different combinations of those technologies are described for polymetallic sulfide concentrates, low-grade sulfide and oxidised ores. Three areas for further research are: (i) the development of sophisticated continuous vat bioreactors with additional controls; (ii) in situ and in stope bioleaching and the need to solve problems associated with microbial activity in that scenario; and (iii) the exploitation of sulfur-oxidising microorganisms that, under specific anaerobic leaching conditions, reduce and solubilise refractory iron(III) or manganese(IV) compounds containing multiple elements. Finally, with the successful applications of stirred tank bioleaching to a polymetallic tailings dump and heap bioleaching to a polymetallic black schist ore, there is no reason why those proven technologies should not be more widely applied.

Nickel is a strategically important metal. Nickel was used much earlier before it was scientifically discovered in 1751 by a Swedish scientist Cronstedt. Nickel is the 24th most abundant element in the Earth's crust, comprising about 3 % of the composition of the earth. It is the 5th most abundant element by weight after iron, oxygen, magnesium and silicon (Cempel and Nickel 2006). The wide applications of nickel in anti-corrosion materials manufacturing, stainless steel and alloy steel production, chemical industries, electrical and electronic equipment, etc. require vast sources of nickel. Sulphidic and lateritic (oxidic) are the two principal types of nickel deposits present in the world.Laterites are oxidic ores extensively found in tropical regions of the world. They were formed by the laterisation process of ultramafic rocks. Laterites are the weathering products of the ultramafic rocks in the earth crust (Le et al. 2006). The warm climate and abundant rainfalls are the favourable environmental conditions for formation of laterites. Lateritic deposits are broadly classified into limonite and saprolite types. Limonites or the oxidic laterites are highly enriched with iron oxides; however, the saprolites are silicate-dominated lateritic minerals (Chang et al. 2010). Majority of the laterites found on the surface of earth crust are limonite [(Fe, Ni) (Simate et al. 2010;Golightly 1981).Lateritic nickel deposits contribute about 80 % of the land-based nickel reserves of the world. However, only 40 % of global nickel is produced from laterites (Valix and Loon 2003). The underutilisation of the vast resources may be attributed to higher processing cost (Thomas 1995). Presently, most of the global nickel

Abstract. Nickel laterite ore contains oxide of iron, aluminum or both with nickel, cobalt and chromium which can be leached out using hydrometallurgical process. For the purpose of meeting the world's increasing demand of nickel, there is a need to invent environmentally friendly process to efficiently leach nickel. This experiment used nickel laterite ore obtained from Pomalaa, South Sulawesi. The leaching agent is metabolic citric acid produced by Aspergillus niger under optimum condition. Leaching process was done in three-necked flask in atmospheric temperature and constant stirring speed of 200 rpm. The variable examined in the experiment was pulp density and particle size of nickel laterite ore. Samples were taken at 3, 7, 10, 14, and 17 minutes and then filtered and diluted to be analyzed using ICP-AES. The result of the experiment showed the maximum recovery of metals increase with the decrease of the pulp density. The maximum recovery for varying pulp density were at 5% solid/liquid ratio and the recovery were Ni at 1.63%, Al at 0.47%, Fe at 0.23% and Mg at 1.09%. The effect of particle size on leaching process showed that the leaching process follows the shrinking core model. The maximum recovery of metals at particle size were at 100-120 mesh with Ni at 1.37%, Fe at 0.10%, Al at 0.72% and Mg at 0.62%.
