Our proprietary WaterShed binders treat the tailings slurry at the point of discharge to create a free draining structure and provide immediate water release which is available for recovery and
Read MoreIn fact tailings characteristics vary greatly and are highly dependent on the ore type clay mineralogy and the physical and chemical processes used to extract the economic product. Therefore a comprehensive understanding of the mechanical properties of mine tailings is critical for the design of a tailing dam.
