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.
