Chat OnlineThe ore is mined from an open pit crushed and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines and the rougher concentrate is transferred to a regrinding stage.
Chat OnlineThis flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed copper depression can be achieved by using sodium sulphide hydrosulfite lime cyanide zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important even critical consideration.
