| Abstract: | A new technological flowsheet of utiliziing red mud from alumina treating plant to produce high quality direct reduction iron is introduced.It is a good way to make use of waste red mud,not only solving the problem of pollution cansed by red mud but also bringing great profits.The direct reduction iron produced with a metallization rate of 92 1%,an iron content of 92 7% and an iron recovery rate of 94 2% can be used as feed for electric furnace to produce steel. |
