In the Spotlight – Crystal Growth Modifiers

In the competitive environment of alumina refining, processing plants are continuously challenged to increase yield while maintaining hydrate crystal size and quality.  Nalco Water offers crystal growth modifier (CGM) programs that are specifically designed for use within the precipitation circuits of the Bayer process.  The programs provide additional control of agglomeration and nucleation mechanisms, which can positively impact final product size control, liquor yield, hydrate classification, and oxalate interference control.  

Crystal growth modifiers are just one example of Nalco Water's comprehensive portfolio of mineral processing aids. Contact us to discuss your specific operational needs and learn more about our mineral processing solutions.
