  • GOLD ADSORPTION ON ACTIVATED CARBON AND THE EFFECT

    The adsorption of gold cyanide from clear solutions was found to be characterized by intraparticle diffusion rate control limited by a finite film mass transfer rate at low gold loadings When fine suspended solids are present it is shown that blinding of the carbon macropores is the likely cause of the reduced adsorption rate Although the
