安徽某多金属硫化矿选矿工艺研究

摘要

安徽某硫化矿是以硫为主,伴生铜、金、银、铁等多种金属的大型矿山.针对该矿特点,选择铜优先浮选-浮选尾矿磁选铁-硫精矿焙烧制硫酸-硫酸渣氰化浸出金和银的工艺流程,得到铜精矿品位20.39％,硫精矿品位50.85％,金的总回收率80.81％,银的总回收率70.66％,铁精矿品位64.44％的较好选矿指标.研究结果为该多金属硫化矿提供了一套经济合理、技术可行的工艺流程.%In a certain place in Anhui polymetallic sulfide ore is high-grade sulphur associated copper, gold, silver, iron elements. Against the ore characteristics, copper-selective flotation-magnetic separation of flotation-tailing-roasting of Sulphur concentrade-cyanidation of Acid-residue is flowsheet and the final results: copper concentrate grade 20.39%, Sulphur concentrate grade 50.85%, the gold total recovery 80.81%, the silver total recovery 70.66%, iron concentrate grade 64. 44%. The flowsheet is fit for the multi -metal sulfide minerals to provide a economical and reasonable, technically feasible.
