摘要
Abstract
Resarch on Beneficiation experimental study of lirmmite ore in Guangxi is presented in thia paper.according to the ore propertly which iron grade is relatively high.and S.P content is relatively low, series beneficiation methods are adopted for the experimental study which are single gravity concentration.magnetic separation.oxidizing roasting-high imensity magnetic separation.reduction roasting-low intensity magnetic separation.The test result shows, if only adopting single gravity separation by tabling or high intensity magnetic aeparation, the iron concentration gade and recovery are low.the selective recovey result is bad; if adopting oxidizing roasting-high intensity magnetic separatjon process, oxidizing roasting can improve the raw ore grade to 57％ , and the improvement result of ore grade by high intensity magnetic separation is bad; if adopting reduction roasting-low intensity magnetic separation process.the concentrate grade is TFe 59.77％.and the recovery is 77.24％.关键词
