    Flotation is a separation process to produce copper-gold concentrate. Concentrate slurry consisting of finely ground ore and water mixed with reagents is introduced into a series of mixing tanks called flotation cells, where air is pumped into the slurry. The reagents used are lime, frothers and collectors

    Aug 01, 2019 The commonly used technology for copper-bearing ore separation is froth flotation (Liu et al., 2019a, Liu et al., 2019b, Liu et al., 2017). As flotation is a water-intensive process, many flotation plants attempt to use recycled water, or sea water as an alternative due to the fresh water shortage (Hirajima et al., 2016, Wang and Peng, 2014)
