INFLUENCE OF ADDITIVES ON SLAG-IRON SEPARATION DURING DIRECT REDUCTION OF COAL-BASE HIGH-IRON-CONTENT RED MUD

摘要

The influence of additives on slag-iron separation when high-iron-content red mud was directly reduced by coal was researched. The results showed that a relatively satisfactory index can be gained by the following conditions: the amount of oxygen-type additive is 3%, reducing time is 120 min and the reducing temperature is 1 473 K.
