Performance Benefits 

• The Rheomax^® DR range of flocculants create a high density and more robust aggregate compared to conventional products, which are effective on a wide variety of mineral ore types. This change in aggregate shape allows for faster consolidation, high underflow densities and low underflow yield stress
• Benefits are 
• Improved water recovery (up –to 70%*; up-to 20%**) at the thickener to be reused in the process, leading to less fresh water consumption 
• Less volume of waste water leading to a lower residue footprint and less evaporation of water at the Tailings dam
• CCD washing efficiency is increased and recovery of leached metal is improved
• Energy can be saved due to reduced pumping pressure
• Decrease in chemical consumption compared to standard PAM (up to -20%**)
• Ability to perform in highly saline and high iron environments where conventional chemistry doesn’t work
