The invention discloses a method for sorting lead-zinc oxide ore with the high oxidation rate, and belongs to the technical field of metallurgy. The method comprises the specific steps that the lead-zinc oxide ore with the high oxidation rate is subjected to crushing and ore grinding until the lead-zinc oxide ore with the granularity being -0.074 mm accounts for 70%-95% for standby application; adispersing agent, a vulcanizing agent and a collecting agent are added into ore pulp of the lead-zinc oxide ore with the high oxidation rate after treatment for lead recovery flotation, a technological process of one-time roughing, two-time scavenging and two-time concentration is adopted, middling ore returns orderly, and lead oxide concentrate and lead flotation tailings are obtained; then the dispersing agent, the vulcanizing agent and a KM301 zinc oxide collecting agent are added into ore pulp of the lead flotation tailings, a technological process of two-time roughing, one-time scavengingand two-time concentration is adopted, zinc concentration II tailings return to zinc roughing II, zinc concentration I tailings directly return to scavenging operation, and other middling ore returnsorderly, so that zinc concentration and tailings are obtained. According to the method for sorting the lead-zinc oxide ore with the high oxidation rate, the technology is simple, the process is short, and the efficient zinc oxide collecting agent KM301 is adopted and has the characteristics that selecting is good, the recovery rate is high, medicament consumption is small, the influence by fine slit is small, and the environmental protection and non-toxic effects are achieved.
