ALUMINA, BAUXITE AND WATER

Today’s alumina & bauxite producer is constantly challenged to improve safety, profitability, efficiency, product quality and the environment.

Water plays a critical role in virtually all mining and mineral processing activities. It is a strategic resource with decreased availability and growing demand. Most of the water in the Bayer process must be evaporated, increasing energy consumption. More than ever, the industry requires solutions that demonstrate sustainable, ongoing water management.
