The first stage of solution precipitation is Cu removal. Cu is cemented using Zn dust, and Cu 2 O is produced. Reducing the Zn dust consumption is important from operating costs. The Cu cake is sent to Cu smelters. 3.4.4 Cl Removal. If the solution Cl content is high, it should be removed at the Cu removal stage.
