In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached.An associated process isLive Chat

    • Low temperature aqueous alteration of basalt Mineral

      Kaolinite formation requires leaching by relatively fresh water with low silica and base cation activities, so input of meteoric waters, as opposed to solely groundwater, promotes the formation of kaolinite over smectite [e.g., Wilson, 1999]. On Mars, the presence of kaolinite, if formed through leaching, would similarly require freshwater.
