SLURRY PUMPING AIDS / RHEOLOGY MODIFIERS
Pumping mineral slurries over long distances can be very costly as a result of the energy required to move the slurry or dilution to minimize energy requirements. Slurry pumping aids such as dispersant viscosity modifiers or rheology modifiers work to reduce the rheological properties of the slurry, while allowing for increased slurry solids to be transferred over greater distances. A good example of this can be found in the transfer of phosphate concentrate to the phosphoric acid chemical plant which can be hundreds of miles away.
Rheology modifiers also assist in preventing or reducing the cementation process which can occur in the slurry pipeline due to downtime in the transportation process. A rheology modifier will allow for the slurry to redisperse upon restarting the plant, instead of cementing or compacting at the bottom of the pipeline.
Some minerals require a stable dispersion for transportation in drums as they are shipped across the world. If shipped in the absence of a dispersant viscosity modifier or rheology modifier, the drums will also develop some level of cementation.
ArrMaz custom formulates dispersants, viscosity modifiers and rheology modifiers for specific ore types to optimize the slurry pumping process. Let us help you select and plant test the best slurry pumping aid for your process. We will work closely with you to ensure a successful outcome for your project.
