mining gold from water with carbon filters

  • Industrial Water Filtration for Mining, Oil & Gas Production

    The absorptive properties of activated carbon are due to the micro-porous structure of each grain resulting into large surface area per unit column of carbon. In the gold industry, activated carbon is utilized in CIP/ CIL process to transfer dissolved gold from cyanide leached slurry to elution column where gold is desorbed from the carbon.
