On top of that, the steelmaking process requires breaking the chemical bond in iron ore to get access to pure iron, a reaction that requires a reagent to bind with oxygen. Broadly speaking, in the last 2,000 years of steelmaking, that reagent has been coal, which generates CO 2 as a 1 Iron ore comes in two forms, either hematite ...

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...
