14/03/2014· The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface. Open pit
Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective.
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked

It produces 9 Mtpa of iron ore concentrate, of which 80% is trucked to it's own steel plant nearby. The remaining ore is railed to other ArcelorMittal affiliates in Eastern Europe as well as to third parties. Kryvyi Rih has benefited greatly from the devaluation of its local
Surface iron ore mining in eastern India and local level sustainability. Iron ore mining in eastern India significantly contributes to India's national economy but it also degrades the surrounding environment. The national policies reviewed, so far, highlight that unless local level sustainability is maintained an incomplete picture of economic prosperity is obtained. So far, explicit
The large fleet of surface miners consisted of Wirtgen 2500SM’s, 4200SM’s and both Vermeer T1255s and T1655s. Global’s production target was to mine 9 million tonnes of ore per month, making it the largest surface mining operation in the world.

It is a cheaper procedure to extract the iron ore
Mining Underground mining. Underground mining. When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.
Most iron ores are extracted by surface mining. Some underground mines do exist, but, wherever possible, surface mining is preferred because it is cheaper. Lumps and fines Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch).
