biobeneficiation of mineral sulphide

  • Biooxidation BioMineWiki

    In biooxidation or biobeneficiation the undesired metals and other compounds are leached away from the ore. 1) Two types of sulfide ores. To the left sulfur (yellow) is bound to a metal (green) for example copper. To the right sulfur (yellow) is bound to a metal (blue) for example iron. Elemental metal (red) for example gold is enclosed/trapped/hosted in the sulfide matrix to the

  • Application of biotechnology in iron ore beneficiation

    Research into the biobeneficiation of sulfide mineral systems was driven by a desire to use bioreagents to replace or augment xanthate and fatty amine collectors to upgrade the ore as these conventional collectors are expensive and environmentally damaging. In addition there was a possibility that microorganisms and their metabolites could be used to assist or replace environmentally

    The principal sulfide mineral of nickel is pentlandite [(NiFe) 9 S 8]. Nickel is also found to a minor degree in violarite (Ni 2 FeS 4) and pyrrhotite (Fe 7 S 8). Compared with laterite ores sulfide ores have a much lower amount of moisture and may contain many different metals in the same ore.
