To enrich the iron share of the ore, for example through flotation and/or magnetic separation, it is necessary to first grind the ore to a workable grain size. The fine grain concentrate (dK < 100 μm) must be converted into lumps in a separate process so that it may be later smelted in a blast furnace.
