Cost of raw and auxiliary materials in the alumina production costs accounting for 30-35%, and a great impact on cost. And bauxite alumina content is high, but lower A / S, so the high cost of consumption of aluminum ore. Determined at the same time, due to the characteristics of the ore, soda ash consumption is relatively high, accounting for about 50 percent of the cost of raw materials. So how to tap the potential of great significance to reduce the cost of alumina production from a management and technical perspective.
