Abstract
High calcium type tin , iron-bearing tailing is recognized as one of typically complex iron ore resources in China. A process of magnetizing roasting process followed by magnetic separation was used to utilize the tailings in our previous paper. Under the optimal conditions, qualified magnetic concentrates were obtained and could be used for direct reduced iron production. In this study, the phase transformation of these tailings during the magnetizing roasting process was investigated. And the reaction behavior between calcium oxide and iron oxide was revealed by using XRD, TG-DSC, VSM, etc. The results indicated that calcium ferrite was easily formed under CO–CO2 atmosphere , which has an unfavorable effect on the separation of iron and tin oxides from the tailings.
