Ore Grinding Millsare used for the finegrindingas the last step in the reduction of anoreprior to concentration (gravity or flotation) or cyanidation.Practice varies, depending upon the type oforeand the amount of reduction required. In addition, some of the older properties continue with methods that perhaps are not considered the best in light of recent improvements but that cannot be

Important advances have been made in the last 60 years or so in the modeling of ballmillsusing 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 ironore
