This invention discloses a method for the comprehensive utilization of sulfide tailings, relating to the field of sulfide tailings treatment technology. This method uses lead-zinc tailings as raw material and innovatively employs a combined "two-stage acid leaching-gravity separation-flotation" process. First, two stages of acid leaching selectively leach calcite associated with barite in the tailings, reducing the influence of muddy calcite while activating pyrite. Subsequently, the acid leaching residue undergoes gravity separation to further separate undissolved calcite, quartz, and other silica-containing gangue minerals. The gravity concentrate is then subjected to flotation to achieve the separation of barite and pyrite, ultimately obtaining high-purity barite and pyrite products respectively. This invention features a reasonable process route and simple operation, effectively solving the separation problem of fine-grained, high-viscosity lead-zinc tailings, achieving full-component purification and utilization of lead-zinc tailings, significantly enhancing the economic value of tailings resources, and reducing the environmental pressure caused by tailings stockpiling, thus demonstrating good economic, environmental, and social benefits.
