本文叙述1975年6-9月作无氰浮选小型与工业实验成果,并对结果作了分析与探讨。作者认为,对于那些黄铁矿含量少或黄铁矿易被抑制的铅锌矿石,采用优先浮选而不用氰化物作抑制剂是可行的,但对于那些含量大且可浮性好的黄铁矿的矿石,如果完全不用氰化物则要从药方与流程等来考虑。 This article describes the experimental results of small and industrial non-cyanide flotation from June to September in 1975, and analyzes and discusses the results. The authors argue that the use of preferential flotation instead of cyanide as a suppressant is advisable for lead-zinc ores with little or no pyrite content, but for those with high content and good flotation Mine ore, if you do not have cyanide from prescriptions and processes to consider.
