According to introducing, the present invention belongs to the short flow concentration, provides an economic, applicable, simple, and separation effect is very good and refractory copper zinc sulfide ore float separation technology, the main steps including copper, selection of zinc. Researchers used LP-02 as copper mine of content of collector, and with LY-02 as gravity selection.both the inhibitors and pyrite mine, in a neutral medium conditions the copper sulfide priority flotation thing; Choose the CuSO4 with zinc as activator, butyl xanthate as of collector, and by subsection adjust PH pulp, namely, in control when the coarse select pulp PH in 9 ~ 10, between pulp PH in selected increase on 10 to 11 between.
 

Currently used more copper zinc priority flotation technology copper concentrate production quality is low, the production cost is high. This invention and adaptability is strong, stable production index, not only can recycle copper, and can significantly improve the quality of copper and zinc concentrate with copper, zinc is, and greatly reduce the production cost, improve profitability, polluting the natural environment, accord with energy conservation and cleaner production requirements.Recently, jiangxi university of science and technology and scientific research personnel LuoXian equal invented a kind of refractory copper zinc sulfide ore flotation separation technique obtains the national invention patent license, solve the existing copper flotation process-zinc concentrate the poor quality of separation, high cost, mineral resources waste of difficult problems.
