This report deals with the materials balances and energy consumption data for the production sequence resulting in the output of primary aluminum ingots. The ingot are formed by casting the molten aluminum obtained from smelting are suitable for subsequent fabrication of products. This study describes production of primary aluminum ingots, including mining of bauxite, refining bauxite into alumina, and smelting alumina into aluminum. Other data cover production of soda ash, lime, petroleum coke, cryolite and fluorspar, and caustic; energy requirements and consumption and the effect of raw materials imports.
