Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.
Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers. Iron ore sample found is a part of banded iron ore .
Energy and Environmental Profile of the Mining Industry Process Overview Copper Ore Mining Copper is commonly extracted from surface, underground and increasingly, from in situ operations.

Jun 19, 2019· Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.
Iron is produced from iron carrying higher quantity of hematite or magnetite are called natural ore and can be directly fed into blast furnace for the extraction of iron ore mining process, rocks carrying high quantity of ore are identified, followed by drilling blast holes in the rocks.
Sep 26, 2014· Iron ore is one of the top three commodities mined in the world. The raw material, which is typically found in rocks and minerals, is rich in iron oxides and usually found in the form of magnetite, hematite, goethite, limonite or siderite.
