The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Most of the large iron ore mines are mechanized mines. In these mining is done to extract iron ore from surface deposits. In these mines all the operations are mechanized and mining is invariably done through systematic formation of benches by drilling and blasting. Mining process. The recovery of material is done from an open pit in the ground.

How iron ore is mined. LKAB's mining method, sub-level caving, leads to the formation of cavities in the rock when the iron ore is mined. These cavities are then filled with waste rock that collapses down. This causes automatic clogging, and the more ore that is mined, the more the mountain above sinks. The ground surface is affected and ...

Introduction. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers replaced ...

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." Blast furnaces require many auxiliary facilities to support their operations.
