thickening iron ore tailings

For example, a tailings stream in an iron ore application could be thickened to 45–50% solids Newtonian slurry in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65–70% solids non-Newtonian suspension using a paste thickener. Water Recovery

    Dry tailings plant Metso Outotec

    Dry Tailings Plant product consist of thickening, filtering and dry material handling processes. A Thickener Plant will dewater the tailings from very low solids density to medium and high density. As an example from 5 % w/w solids up to around 65 to 70 % w/w solids for an iron ore tailings. The Thickened Tailings slurry is then pumped to ...

    Abstract: The first industrial iron ore extraction in Brazil occurred in the Quadril tero Ferr fero. Those areas most conducive to tailings disposal have been occupied over many years of operation; in the remaining areas there are many constraints that greatly hamper conventional tailings disposal.

    Water shortages and environmental pressures make consideration of thickening tailings to solids concentrations within the paste range necessary in most new tailings projects. The paste thickeners at the DeBeers CTP plant in Kimberley, South Africa are an example of paste tailings disposal on the surface, also called “stacking” (Houman, 2003).

    Iron ore tailings dry stacking in Pau Branco mine Brazil

    Abstract The mining industry has seen several significant dam failures in recent years. Dam failures are associated with errors in design, implementation, operation, and monitoring (Azam, 2014, [2]). Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines in Brazil ...
