  • The Newest Gold Mining Tool: Bacteria - Advancing Mining

     · On the way “We’ve known that this process takes place, but for the first time we’ve been able to show that this transformation takes place in just years to decades — that’s a blink of an eye in terms of geological time

  • Bacteria produce gold by digesting toxic metals

     · High concentrations of heavy metals, like copper and , are toxic for most living creatures. This is not the case for the C. metallidurans, which has found a way to valuable

  • This Bacteria Eats Toxic Metal, Poops Gold Nuggets

    The is famous, biologically speaking, for being able to survive massive doses of toxic

  • Bacterial Leach | Mining | SGS

    In bacterial leaching, certain strains of bacteria are used to liberate gold or base metals from their mineralogical host. They metabolize energy from the oxidation of ferrous iron and/or sulfur compounds and free gold or metals in the process. This can take place in a heap, vat or column of crushed or ground ore

  • Isolation and characterization of cellulose-degrading

    The present study investigated the cultivable mesophilic 37 degrees C and thermophilic 60 degrees C cellulose-degrading diversity in a weathered soil-like sample collected from the deep subsurface 1.5 km depth of the Homestake mine in Lead, South Dakota, USA. Chemical characteri

  • Gold extraction

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it d

  • Mining: Bacteria with Midas touch for efficient gold

     · "In the natural environment, primary gold makes its way into soils, sediments and waterways through biogeochemical weathering and eventually ends up in the ocean. On the way bacteria can dissolve

  • Bacterial Leaching – Core Group

    > Leaching Core has extensive experience in testwork relating to bacterially assisted leaching of base metal sulphide and refractory ores. Test programmes carried out have included use of a range of bioreactors for oxidation of concentrates and aerated columns for heap leach simulation studies
