N2 - The presence of copper aqueous (+2) in the pulps that feed the flotation circuits is due to the oxidation of the copper contained in sulfides (chalcopyrite) and in oxides (malachite) as a result of the galvanic reactions that occur during grinding copper aqueous (+2) can have a negative effect during the collectorless flotation of galena. In this investigation, the galena concentrated by collectorless flotation and in the presence of copper aqueous (+2) in alkaline media was superficially characterized by infrared spectroscopy. The results show the depression of galena with the increase of the dosage of copper aqueous (+2) in the pulp at pH 9.6 and Eh of +120 (mV). From the infrared characterization, it was found that the surface state of the galena when it undergoes depression, shows the absence of some of the absorption bands corresponding to the Pb-O and Pb-OH bonds of lead oxide and hydroxide detected when galena flotation reaches maximum recovery.
