Today’s alumina and bauxite producer is constantly challenged to improve safety, profitability, efficiency, and product quality while helping to sustain the surrounding environmental resources. 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, which ultimately increases energy consumption.
Nalco Water addresses this challenge head-on, with alumina processing aids that maximize productivity while minimizing water and energy consumption. With global success across a variety of alumina refining operations, Nalco Water tailors solutions that meet the unique needs of water-constrained environments.
Nalco Water is a partner that delivers economic and environmental value. By focusing on the entire alumina refining process, we help increase recovery and productivity while conserving energy, water, and raw materials. Using our alumina processing aids, our approach results in optimized productivity and throughput, which can positively impact our customers' bottom line. We use decades of industry experience, innovative technologies, local on-site expertise, and a global network of research labs and personnel to deliver the alumina processing results you need.
Scale Formation is one of the most critical challenges to control the mud settling performance in a lead washer and to extend the vessel life. ScaleGuard™ was trialed at Rio Tinto Yarwun alumina refinery with promising results.
At Hindalco’s Muri alumina refinery in India, ScaleGuard™ was applied to the first washer to extend the washer life and improve overall efficiency of caustic recovery.
