The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process. Aiming towards the good quality (>60% Fe) ore and its non-renewable nature, the mineral rich ore is depleting, and the slimes are increasing at a rate of ∼11–13% for the hematite reserves in India, as reported by the ...
Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.

IndIan Iron ore resources: Indianironores generallycontain hematite,magnetite,limonite and siderite minerals. In the total iron ore reserves of about· 17.712 billion tonnes, hematite is about 12.3 billion tonnes
Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...
