| description | The invention discloses a multi-metal lead-zinc sulfide ore flotation separation method based on a composite inhibitor, and belongs to the technical field of ore dressing. The method specifically comprises the following steps: (1) firstly, carrying out ore grinding and grading on jamesonite and marmatite-containing minerals; (2) after the raw ore is subjected to primary roughing, concentrate is subjected to secondary concentration operation, and lead-antimony concentrate is obtained; and (3) carrying out scavenging operation for three times to obtain zinc-containing tailings. The invention provides a novel organic inhibitor DL-cysteine, and adopts a process of one-step roughing, two-step refining and three-step sweeping, so that high-efficiency separation of lead and zinc can be realized, and environmental pollution is effectively reduced. The problem that the environment is polluted due to the fact that a large amount of cyanide needs to be used as an inhibitor for separation of jamesonite and marmatite is s |
