Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.

Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...

For ore bodies having dips in between these, special designs are required. The openings made in the process of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is ...

Download. Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

Interact with the furnace and place the iron ore in the top slot. Place wood, coal, or other flammable items in the bottom slot. Over time, the fuel will burn away and the ore will become iron ingots.
