Universal reserves of high-grade ores are diminishing at an alarming rate due to the rapid increase in the demand for metals. Biomining is the extraction of specific metals from their ores through biological means, usually microorganism. Biomining is done in two steps often called bioleaching and biooxidation.

Abstract Extraction of metals by the application of bioleaching methods holds great promise. Various physicochemical parameters, such as the biomass availability of CO 2 , particle size, mineralogy of the ore, and pulp density, influence the bioleaching rates.

The effect of sequential leaching such as bioleaching followed by bioleaching and bioleaching followed by chemical leaching is aimed at enhancing metal (Mo, Ni, V and Al) dissolution from a differently pretreated (acetone washed/decoked) spent catalyst.

Investigating heap bioleaching: Effect of feed iron concentration on bioleaching performance
Minerals Engineering, 2010Abstract This paper describes an investigation into the effect of iron concentration in the leach solution on the bioleaching of a low grade copper ore, where chalcopyrite was the dominant copper sulphide. The concentration of dissolved iron is primarily controlled by pH and the relative proportion of ferric to ferrous iron, with significant jarosite

BioSigma Bioleaching Seeds (BBS): A New Technology for Managing Bioleaching Microorganisms
Advanced Materials Research, 2013In Bioleaching, although it is already prove that chalcopyrite can be dissolved by microorganisms, a major task is to do it efficiently in economical terms at industrial scale. BioSigma Bioleaching Seeds (BBS) represents a biotechnological breakthrough for the production of bioleaching solutions on demand with high concentrations of biomining ...

Discrete particle size fractions of a zinc sulphide ore were bioleached in stirred tank reactors operated in batch mode. Kinetic analyses of these tests revealed that the leaching process was divided into two stages: (1) a period of colonization of the ore by bacteria, and (2) a steady rate period where the reaction could be described by classical ...

Electrochemical Applications in Metal Bioleaching
2017Biohydrometallurgy comprises the recovery of metals by biologically catalyzed metal dissolution from solids in an aqueous solution. The application of this kind of bioprocessing is described as "biomining," referring to either bioleaching or biooxidation of sulfide metal ores.

Enargite (Cu₃AsS₄) is a refractory mineral that has not been investigated extensively with respect to copper leaching. The two main challenges to its leaching is its very refractory nature, which some sources consider to be more refractory than chalcopyrite; and the mineral contains arsenic, and possibly small amounts of antimony, which will pose a ...
