Title:
ARSENIC-SULFUR SEPARATION METHOD FOR ARSENIC-TIN-LEAD-ZINC-ANTIMONY POLYMETALLIC ORE
Document Type and Number:
WIPO Patent Application WO/2024/027132
Kind Code:
A1
Abstract:
An arsenic-sulfur separation method for arsenic-tin-lead-zinc-antimony polymetallic ore, comprising the following steps: (1) recovering pyrrhotite from zinc tailings by means of magnetic separation; (2) separating arsenic and sulfur from pyrite and arsenopyrite by means of a flotation process to obtain a sulfur concentrate and an arsenic concentrate; and (3) obtaining fine-grained tin concentrate by means of gravity separation (shaker) from fine tin that may be present in the arsenic concentrate. The present method can be used to comprehensively recover sulfur, arsenic and tin from lead and zinc flotation tailings to comprehensively utilize resources, reduce tailing emissions, and mitigate environmental pollution.
