Aug 15 2020 Iron Production. The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities iron .

During ironmaking iron ore coke heated air and limestone or other fluxes are fed into a blast furnace. The heated air causes the coke combustion which provides the heat and carbon sources for iron production. Limestone or other fluxes may be added to react with and remove the acidic impurities called slag from the molten iron.

Iron ore is the key raw material for steel production enterprises. Generally iron ore with a grade of less than 50 needs to be processed before smelting and utilization. After crushing grinding magnetic separation flotation and gravity separation etc. iron is gradually selected from the natural iron ore.
Iron ore is mined in about 50 countries. The seven largest of these producing countries account for about three-quarters of total world production. Among the largest iron ore producing nations are Russia Brazil China Australia India and the USA. Iron is one of the three naturally magnetic elements the others are cobalt and nickel.

In this study oxidizing roasting segregation roasting and magnetic separation are used to extract cobalt and iron from refractory Co-bearing sulfur concentrate. The Co-bearing sulfur concentrate containing 0.68 Co 33.26 Fe and 36.58 S was obtained from V-Ti magnetite in the Panxi area of China by flotation. Cobalt pyrite and linneite were the Co-bearing minerals and the gangue .
