Copper Ore Crushing, Grinding Flotation

2017-5-21  A second source of water to the grinding section is derived from fresh water to the crushing and ore storage dust collection systems when operating. Flotation consists of one stage of rougher flotation of three cells, three stages of rougher scavenger flotation and one stage each of cleaner (3 cells), recleaner (2 cells) and cleaner scavenger flotation (3 cells).
