A low-grade manganese carbonate ore in Tongren of Guizhou Province has complicated mineral compositions, with a higher content of clay mineral illite (19.30%). In order to improve the mineral dressing index of this type of manganese ore resources, magnetic separation experiments was performed for it by using a high gradient magnetic separator. In the experiment, the mineral after pre-desliming was ground by a ball mill to a grinding fineness of -75 μm 69.62%. Then, it was subjected to a magnetic separation process consisting of one roughing and two scavenging, resulting in the final manganese carbonate concentrate grading 19.39% Mn at 83.66% recovery, with yield of 52.81%. The experiment results are of great significance for reducing the discharge of electrolytic manganese slag in Tongren.

贵州铜仁地区某低品位碳酸锰矿矿物组成复杂，黏土矿物伊利石含量较高（19.30%），为了更好地提高该类型锰矿资源的选矿指标，对其开展了磁选试验研究。结果表明，预先脱泥后通过球磨机磨矿，在磨矿细度-75 μm粒级占69.62%条件下，采用一次粗选、两次扫选磁选流程，最终可获得产率52.81%、锰品位和回收率分别为19.39%和83.66%的碳酸锰精矿。试验结果对实现铜仁地区电解锰渣源头减量排放具有重要意义。

摘要
收起

贵州铜仁地区某低品位碳酸锰矿矿物组成复杂，黏土矿物伊利石含量较高（19.30%），为了更好地提高该类型锰矿资源的选矿指标，对其开展了磁选试验研究。结果表明，预先脱泥后通过球磨机磨矿，在磨矿细度-75 μm粒级占69.62%条件下，采用一次粗选、两次扫选磁选流程，最终可获得产率52.81%、锰品位和回收率分别为19.39%和83.66%的碳酸锰精矿。试验结果对实现铜仁地区电解锰渣源头减量排放具有重要意义。

A low-grade manganese carbonate ore in Tongren of Guizhou Province has complicated mineral compositions, with a higher content of clay mineral illite (19.30%). In order to improve the mineral dressing index of this type of manganese ore resources, magnetic separation experiments was performed for it by using a high gradient magnetic separator. In the experiment, the mineral after pre-desliming was ground by a ball mill to a grinding fineness of -75 μm 69.62%. Then, it was subjected to a magnetic separation process consisting of one roughing and two scavenging, resulting in the final manganese carbonate concentrate grading 19.39% Mn at 83.66% recovery, with yield of 52.81%. The experiment results are of great significance for reducing the discharge of electrolytic manganese slag in Tongren.
