iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth’s crust, and it is the

Tailings are the waste and by-products generated by mining operations. The tailings seen here were pumped into the Gribbens Basin, next to the Empire and Tilden Iron Ore Mines in Negaunee, Michigan, USA. Once the materials are pumped into the pond, they are mixed with water to create a sloppy form of mud known as slurry.

Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gases. Direct reduction refers to processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron.

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

magnetic separation for iron ore. By magnetic separation, two products of iron ore and barite concentrates were obtained by using a high intensity magnetic separator. The fine fraction (-0.125 mm) is about 20% by weight assaying 54.6% Fe, and 3.91% BaO, which needs further cleaning to reduce the barite content to meet the smelter.
