The effect of important parameters e.g. conditioning time, collector, concentration, pulp, density, temperature, pH, particle, size, quality collector ,chain, length and cyandiation were studied thoroughly on the adsorption of xanthane ions and the subsequent floatation of chalcopyrite. Stepwise enhancement in upgradation and recovery was achieved by employing these parameters. After fully optimizing the parameters, the copper contentmwas upgrated from 0.8% to 18.75% achieving a recover of 85.25%.
