Iron and aluminum in red mud were recovered by a reductive sintering–magnetic separation–digesting process. The raw materials were composed of ordinary Bayer red mud, MgO, Na2CO3 and C, in which MgO and Na2CO3 were used as mineralizing agents, and C as a reductive agent. Sintering orthogonal experiments …

Magnetic separation is the process of separating magnetic materials from non-magnetic materials using a magnetic system. After World War II, this process became popular in scrap yards to separate metal particles from vehicles; however, the process is more sophisticated than that. In fact, one of the major benefits of magnetic separation …
