Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.
The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

The iron ore mining is a complex and a very long process. There are various tasks involved in the iron ore mining. The first step involves the iron ore is crushed into small pieces. The obtained crushed ore in the send to the grinder followed by the scrubber.
Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.

MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Iron ore mining Working with Iron Ore industry to improve recovery. Schenck Process has been active in iron ore mining for more than 20 years by providing its special separation and vibrating solutions to enhance the iron ore recovery rate.
The process of mining low-grade iron ore, or taconite, requires massive resources.Heavy industrial mining equipment, expansive mines, and a skilled labor pool are all required. Some of the equipment includes diamond-bit rotary drills, hydraulic shovels and loaders, water-wagons, production trucks and heavy duty conveyors.
Top Iron Ore Producing Countries In The World China, followed by Australia and Brazil are the three top ranking iron ore producing countries in the world. Iron ore being extracted at the massive Mikhailovsky Mine in Russia.
Iron ore is the key component in steel, the most widely used of all metals. In South Africa our iron ore operations are made up of a 69.7% shareholding in Kumba Iron Ore Limited (Kumba), a leading supplier of seaborne iron ore. Kumba is listed on the Johannesburg Stock Exchange and operates three mines.
Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.
Iron Ore Mining Process primarily for the production of powdered Iron Ore. Iron can be used to produce small metal parts, to avoid large pieces of iron waste; iron can be used for chemical experiments, which is chunks of iron impossible.
Introduction to Iron Ore and Steel Smelting Processing. Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter.
