What are iron ore fines? Fines is the product name for fine iron ore grains (size 0-6 mm) for use in sintering processes (see below). 20 percent of the iron ore LKAB produces are magnetite fines (MAF), which contain more than 70 percent iron. It is a highly effective alternative to for instance hematite fines.

Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity.
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …
Mining. Most iron ores mined today comprise the iron oxide minerals hematite, Fe 2 O 3 (70% Fe); goethite, Fe 2 O 3 s H 2 O, (63% Fe); limonite, a mixture of hydrated iron oxides (up to 60% Fe); and magnetite, Fe 3 O 4 (72% Fe). As with most iron ore mines throughout the world, all the major Australian iron ore mines are open cut.
KIOCL Limited (Formerly known as Kudremukh Iron Ore Company Limited), a Flagship Company under the Ministry of Steel, Govt. of India was formed on 2 April 1976 for mining and beneficiation of low grade iron ore at Kudremukh, Karnataka, India.KIOCL has been a pioneer with over four decades of experience in operating Iron Ore Mining, …
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.
These steps vary with the respective raw material—for example, ore processing consists of crushing and grinding. For bulk material (eg, iron ore) once …
