Lime use and functionality in sulphide mineral flotation
Nov 01, 2019 The use of lime for pH control is critical to the process. At Newcrest Telfer Cu-Au mine (Australia), sequential flotation is used, in which pyrite is depressed first (by using lime and cyanide), and re-activated (with CuSO 4) prior to a second flotation stage (Benson et al., 2007). This is due to the unique copper-gold orebody at Telfer, which ...

flotation process Infoplease
flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
