Magnetic separation tests were carried out by adopting a pulsating high gradient magnetic separators (HGMS) for low-grade manganese rhodochrosite ores from Yingjiang County of Yunnan Province, with more than 50% passing size of the raw ore finer than -0.019 mm, TMn grade of 6.72% and manganese carbonate content of 84.97%. Based on the laboratory test applying a SLon-100 type cyclic pulsating HGMS, a pilot test was conducted with a SLon-500 type vertical ring pulsating HGMS, by adopting an optimized processing flowsheet consisting of one roughing, one scavenging and a cleaning process of the scavenging concentrate, a manganese concentrate was produced with TMn grade and recovery of 16.77% and 87.61%, respectively.
