What technology makes it possible? “Possibly Top Mining”

The latest technologies that improve mining and mineral processing efficiency and significantly reduce the emissions and effluents will be briefly reviewed. In this sense, the paper point out that the water treatment using techniques such as nanofiltration through membranes to achieve purity levels equal to the incoming water supply is now possible and examples of how this is done will be presented. Membrane technology using nanofiltration can be effectively used for recovering valuable products in water from mining operations and also to remove contaminants. The resulting water is of prime quality equalling potable water standards. The technology can be adapted to most mining operations.
