ABSTRACT
In this paper, a semi-industrial experimental study on a lead-zinc ore with a high oxidation rate in southern Shaanxi is carried out. Based on the lead-zinc flotation process flow in which the lead oxide ore and sulfide ore are mixed together, and the zinc oxide ore and sulfide ore are mixed together to float the lead-zinc flotation process, applying the new beneficiation agent, and finally, the obtained lead grade in the lead concentrate is 22.33% under the premise that the raw ore grades of zinc and lead are 2.39% and 0.46%, and the oxidation rates of lead and zinc are 14.77% and 78.54%, respectively. The recovery rate is 48.76%, the zinc grade in the zinc concentrate is 43.61%, and the recovery rate of zinc is 80.44%. It provides reference and guiding significance for the flotation of the same type of high oxidation rate lead-zinc ore.
