    The flotation tailings will be dewatered in a pressure filter and the tailings sent to the Tailings Management Facility (TMF) for dry stacking to emulate the natural glacial features of the area. Overall design target recoveries are 93% Au and 90% Ag with approximately 25% of the Au and 5% of the Ag reporting to the gravity concentrate and the remainder to the flotation concentrate.

    This means that the final design of any tailings facility is always provisional and must be confirmed once tailings production is underway (Blight 1998). Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first

  • Fine Flotation Tailings Dewatering: Reducing Water

    Thickened Underflow Slurried Tailings Storage Facility . 5 The first action taken was to redirect the TUF away from the Dewatering Screen and pump the material directly to a slurried tailings storage facility (“TSF”), as shown in Figure 3, built near the mill. Due to constrictions of the site layout and limits on land use, the small-scale TSF was constructed with substantially less than

Tailings slurries can have a solids content ranging from 40% to 50%. This amount of solid is equivalent to a water content of 150% and 100% respectively, which for most soils represents slurry with fluid properties. Slurries (unrecoverable and
