filter flocculant pregnant leaching slurry

  • Mining Filtration

    the pregnant solution, as described in Pressure Leaf Filter for Pregnant Leach Clarification above, granular activated carbon is added to the leach slurry (pulp) to adsorb the gold. The carbon adsorbs the gold from the slurry solution and is removed from the slurry by coarse screening and elution. The gold free leach solution is then recycled, while the carbon is processed to remove the
