Abstract: Using flotation tailings which were formed during Bayer beneficiation producing alumina as raw materials, using coal and petroleum coke as reductant, and the dry powder of pulp as adhesive, the briquettes material for reduction smelting was obtained by mixing and the suppression. Compressive strength and specific resistance were detected. The results showed that the compressive strength and specific resistance of briquettes are different with changing of types of coal. The compressive strength increases with increasing the content of dry powder of pulp in briquette, but the specific resistance decreases quickly. The changes of reductant proportion, which means the proportion between coal and petroleum coke and all of them is used as reductant at the same time, have no significant influence on the compressive strength and specific resistance.
