The invention relates to a lead-zinc oxide ore flotation inhibitor and application thereof, and belongs to the technical field of mineral processing. The designed inhibitor comprises the following components in parts by mass: 30-80 parts of lignosulfonate, 10-40 parts of assistant A, and 10-30 parts of soluble starch. The application scheme comprises the following steps: a raw ore is finely grinded to particles with a particle size not larger than 0.074 mm; after the particles are more than 85% of total mass of the raw ore, the size mixing is performed to obtain preselected slurry; after the pH value of the preselected slurry is adjusted to 8-11, the lead-zinc oxide ore flotation inhibitor is added for uniformly stirring; and then, a capturing agent is added to obtain a rough concentration of zinc oxide. The inhibitor is reasonable in component design, has dual attributes of dispersion and inhibition, has such advantages as high selectivity, high inhibition capacity, no poison and pollution and convenience for operation and management, and is convenient for large-scale industrial application.
