Abstract

The invention discloses a method for floating micro-fine particle hard-to-separate marmatite. The method can be used for obtaining a good zinc flotation index from micro-fine disseminated grain size of hard-to-separate lead-zinc sulfide ore such as marmatite, pyrrhotite, pyrite, etc. The method comprises the steps: ore preparation and ore grinding, lead roughing, lead scavenging, lead concentration, zinc roughing, zinc regrinding, zinc concentration, etc. The method develops a novel efficient pyrrhotite and pyrite inhibitor XKY13 and an efficient selective marmatite collector XKP001. The inhibitor forms deep selective inhibition for pyrrhotite and pyrite and enables mineral to be hydrophilic. The collector has strong collecting capacity and selectivity for marmatite and strengthening hydrophilic floating-upward of marmatite. The two medicaments realize efficient separation of marmatite and pyrrhotite and pyrite and improve the comprehensive recovery capacity of mineral containing marmatite.

Description

technical field [0001] The invention relates to the technical field of complex lead-zinc sulfide ore flotation, in particular to a beneficiation method for refractory lead-zinc sulfide ore containing iron sphalerite. Background technique [0002] Sphalerite is transformed by the isomorphic replacement of zinc on the sphalerite lattice by iron atoms. The floatability of sphalerite usually depends on the type and content of impurities in the lattice. When the iron content in the mineral increases Higher, its buoyancy becomes worse, mainly due to the increase of mineral lattice parameters, stronger mineral hydration, and lower natural buoyancy. In sulfide deposits containing sphalerite, sphalerite is usually closely associated with sulfide ores such as galena, pyrite, and pyrrhotite, and sphalerite and pyrite are involved in zinc selection. , the flotation separation of pyrrhotite, but due to the small difference in floatability among minerals and the similar flotation environ...
