The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.

Aluminumcontaining minerals in iron ore are detrimental to blast furnace and sinter plant operations. The two major aluminumcontaining minerals in iron ore are kaolinite (Al 2 (Si 2 O 5)(OH) 4) and gibbsite (Al(OH) 3). Some progress has been made in using flotation to separate kaolinite from hematite.

Ore dressing index is a model used to evaluate the quality of mixed mineral products. After substituting the relevant parameters into the function, the output index represents the degree to which the mixed ore is suitable for beneficiation. The model is related to the ore's composition, the particle size of the ore, and the grinding time.

The choice of grinding circuit is based on the density and hardness of the ore to be ground. Although use of the rod or ball mill grinding is quite common, a few facilities use autogenous or semi autogenous grinding systems. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the grinding mill.
