摘要
针对云南盈江某低品位菱锰矿-0.019mm粒级含量超过50%、碳酸锰分布率达84.97%的特点,采用脉动高梯度磁选机分选该锰矿。在SLon-100周期式脉动高梯度磁选机探索试验基础上,使用SLon-500立环脉动高梯度磁选机进行半工业试验,采用“一粗一扫、扫选精矿精选”的优化工艺流程,在原矿TMn含量6.72%时,可获得TMn精矿品位16.77%、回收率87.61%的锰精矿。
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.
