Saving Energy in Alumina - Aluminium Plants

Abstract

High energy consumption is characteristic of the industrial production of aluminium. In the , initial, alumina production phase, THERMAL CONSUMPTION is predominant and becomes an important factor in the cost of production when the raw material used is a bauxite with a high diasporic content which, in the instance of existing bauxite reserves on our old continent, is the case. In the, second, aluminium production phase, a high consumption of ELECTRIC ENERGY is predominant. That is why aluminium production is termed an ELECTRICITY HUNGRY INDUSTRY. Successive energy crises therefore forced this industry to reduce, in both phases of production, its energy consumption. Our plant comprises both of these procedures, that is alumina and aluminium production.
