Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,. Most iron ore is produced from open pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant.
Method Of Extracting Iron Ore
This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal like sodium or magnesium, and by electrolysis. Details for the extraction of aluminium, copper, iron and titanium are given in separate pages in this section.

Bioleaching and phytomining are increasingly used to extract copper from low grade ores see below. The traditional method of extraction is to heat the copper sulfide. Copper II sulfide gives copper and sulfur dioxide during
Mining
Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed.
