Abstract
The technology of coal-based direct reduction of high-iron-content red mud is studied. The factors affecting this kind of direct reduction mainly are: coal sort, carbon amount, time, temperature and etc. has been investigated. It has been shown that an ideal coal sort must have the following qualities: high reactivity, large ratio of (F c +V m)/A and (SiO2 +T Fe)/(Al2O3 + Others) and the ability of forming a moderate porosity.
