Recovery of Iron from Tailings of Yangla Copper Ore by Magnetic Separation

Against the dwindling status of mineral resources at present, effective recycling of tailings resources is an effective way to alleviate the shortage of resources, and to improve enterprise efficiency. This study was aimed to recover iron from tailings of Yangla copper ore, Fe content of which was 15.31%, and the content of strong magnetic iron mineral was about 11%. Considering low content of weak magnetic iron mineral and its complex and costly recovery process, weak magnetic iron mineral did not be recovered, so strong magnetic iron mineral was only recovered in this study. Under no grinding condition, Fe recovery of 6.47% with iron grade of 60.87% was obtained. It effectively recovered strong magnetic minerals from tailings, and got enterprise increase additional revenue with good economic benefits.
