May 24, 2016 Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500.
Mar 28, 2015 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.
