  • Process And Plant For The Removal Of Metals By Biosorption From Mining Or Industrial Effluents
    Publication number: 20080142422
    Abstract: A method and a plant to remove metals by biosorption from mining or industrial effluents comprising: (a) subject the effluent to at least one first stage of pre-treatment, selecting among: precipitation by pH rising, solvent extraction or solvent extraction on emulsified membranes in order to reduce its load of metals to a concentration level that allows it to be treated by the next stage of biosorption, and (b) subject the liquid that has been previously in the stage of pre-treatment to a second stage of continuous metals removal by biosorption.
