  • Tailings Paste Disposal – More than Water Recovery

    Tailings Paste Disposal – More than Water Recovery

    For example, a tailings stream in an iron ore application could be thickened to 45-50% solids in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65-70% solids using a paste thickener. This increased water recovery is important to many countries throughout the world due to the scarcity of fresh water

    May 01, 2006 UG2 ore is characterised by repetitive layers of dark, high-density minerals (pyroxene, chromite) and light, less dense feldspars. Typically, the highest grades of platinum group metals (PGM’s) occur at the lower contact zone of the layers, where a strong association with base metal sulphides occurs (specifically nickel, copper and iron)
