Cast- iron spirally arranged shelves assist in raising and showering the pulp through the flames. To both White and White- Howell furnaces an auxiliary fire is often added for roasting the dust which escapes from the main furnace. The dust, when it has been completely roast ed, is shovelled out and mixed with the main bulk of the ore by hand.

The large chunks of stone containing the ore are broken up by giant crushers. 2. These pieces are then fed into rotating roll mills and ball mills which pound and grind the ore into finer particles. 3. After crushing and milling, the valuable iron ore particles can be separated from the waste, using magnetic separators.

Skips, ore bins, and mill equipment can be protected from large pieces of "tramp" iron and steel, such as rockbolts and wire meshes, by electromagnets suspended over conveyor belts (guard magnets) (Figure 2.1). The magnets are generally installed downstream of the primary crusher to protect skips and ore bins.

Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drum-type, or combination feeder at one end and is discharged from the opposite trunnion. Ball mills may be arbitrarily classified into two types, according to the method of pulp discharge.

blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.
