• Tailings.info Surface Paste Disposal

    Paste tailings are defined as tailings that have been significantly dewatered to a point where they do not have a critical flow velocity when pumped, do not segregate as they deposit and produce minimal (if any) bleed water when discharged from a pipe (figure 1).

    Paste Thickening Optimizes Tailings Disposal and Water

    Paste, or thickened tailings, has become an increasingly important method to address many of the environmental problems facing the mining industry. Pasting was originally developed by the alumina industry in the 1970s, and for the past 20 years has been applied worldwide. Yet today, less than 1 percent of iron ore mines employ systems for paste thickening, despite its benefits for tailings

    Tailings Wikipedia

    Paste tailings. Paste tailings is a modification to the conventional methods of disposal of tailings (pond storage). Conventional tailings slurries are composed of a low percent of solids and relatively high water content (normally ranging from 20% to 60% solids for most hard rock mining) and when deposited into the tailings pond the solids and liquids separate. In paste tailings the percent

    Tailings produced from our paste and/or filter tailings system can also be stored underground in previously worked-out voids. The tailings are dewatered and pumped below ground. The paste is often mixed with a binder, such as cement, to provide support to prevent heading collapse and subsidence issues. Any excess paste tailings can be transported to the surface tailings storage facility

    Paste The Future of Tailings Disposal?

    Paste is simply dewatered tailings with little or no water bleed that are non-segregating in nature. It can be ‘stacked’ on surface and the risks associated with dam failure significantly reduces since there is no liquid containment and therefore no mechanism for the tailings to travel for tens of kilometres downstream in the event of a containment failure. The operating costs for the
