Mineral separation method for carbonate rock type high-sulfur copper-lead-zinc ore

The invention belongs to the technical field of mineral processing, and particularly discloses a beneficiation separation method for carbonate rock type high-sulfur copper-lead-zinc ore. In order to solve the problems that carbonate rock type high-sulfur copper-lead-zinc ore is fine in mineral dissemination granularity, uneven in thickness dissemination, complex in symbiotic relation, prone to argillization and floating of gangue and the like, a copper-lead-zinc-sulfur sequential grading and stage grinding flotation process is adopted, and a reagent system is perfectly matched with a mineral separation process; and effective separation and recovery of copper, lead, zinc and sulfur in the carbonate rock type high-sulfur copper-lead-zinc ore are realized. 本发明属于矿物加工技术领域，具体公开了一种碳酸盐岩型高硫铜铅锌矿的选矿分离方法。本发明针对碳酸盐岩型高硫铜铅锌矿矿物嵌布粒度细、粗细嵌布不均、共生关系复杂和脉石易泥化上浮等问题，采用铜铅锌硫依次选别、阶段磨矿浮选工艺，通过药剂制度与选矿工艺的完美匹配，实现了对碳酸盐岩型高硫铜铅锌矿中铜、铅、锌和硫的有效分离回收。
