The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80100 feet high and about 25 feet in diameter (Figure 2) in which the roasted ore, coke ...

Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.

Iron processing Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which ...
