Extraction of Valuable Metals from Red Mud

Article Preview

Abstract:

The reason of comprehensive utilization of red mud is that it contains recycled oxides and a variety of valuable metals. In this paper, the basic characterization of red mud is described. The current developments of extraction of Fe, Ti, Sc, rare earth and valuable metals from red mud are summarized with some emphasis. In addition, the technological features of each process route are analyzed briefly. It can be concluded that it is practiable to extract Fe, Ti, Sc, rare earth and valuable metals from red mud. However, in order to realize recycling of red mud, the key is that an economic, energy saving, environment friendly and widely applicable process has to be found.
