The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

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.
