IOCG Iron Oxide Copper Gold Ore Deposits. IOCG tend to form at 4 to 6 km similar to porphyries and are invariably associated with crustal scale structures. Crustal scale means that they penetrate well down into the crust often 20 km deep and they have strike lengths measured in tens or hundreds of kilometers.
Openpit iron mining The methods and techniques for openpit iron mining depend on several factors such as the stripping ratio, type of mineral, mineralogy and geology, amongst others. However, the most common openpit method is the multiple bench system, which is based on the following operations: drilling, blasting and transport to the treatment plant.
ArcelorMittal Mining Canada. The Mary River deposit is one of the largest and richest known iron ore deposits anywhere, and Baffinland intends to mine between 18 and 30 million tonnes annually from an open pit mine that is expected to operate yearround. Mary River iron ore is said to be among Canada's lowest cost iron ore resources.
India has a large reserve base of minerals and metals (such as iron ore, zinc, lead, bauxite, and thermal coal) it is the second largest global producer of thermal coal and fourth largest producer of iron ore 39; but it has few reserves of metallurgical coal, gold and copper; India's mining sector is underdeveloped
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. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.
