Estimated Water Requirements for the Conventional …
the amount of water required to process copper sulfide ore through a conventional crush-grind-flotation-concentrate circuit ranges from roughly 1.5 metric tons (t) to about 3.5 t of water to process 1 t of ore [Wels and Robertson, 2003, 2004; Misra and others, 2005; Wills and Napier-Munn, 2006; Chilean
Conventional versus mechanized cut and fill mining
Vein width plays a significant role here as well. Mechanized cut and fill generally requires slightly wider veins to accommodate jumbos and load-haul-dumps. As you see in our examples, the mechanized model works on the basis of a vein that is 1 metre wider than that for conventional cut and fill. Grade – Ore grades must support the …
