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.

For treating such a new ore, bulk Cu-Pb flotation followed by Zn flotation has been recommended (Sehlotho et al., 2018). An example of a sequential Cu-Pb-Zn flowsheet is given in Fig. 14 . A first flotation stage is carried out at low pH (pH 6), in which the copper sulphide is floated while both galena and sphalerite are depressed.
