Iron Ore Mining Techniques Metal Extraction
MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

Iron Ore Statistics and Information U.S. Geological Survey
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.

A higher mining skill could also allow for a larger volume of ore to be extracted at the expense of quality, allowing for more, lower quality products to be constructed or increasing the cost for a metallurgist to purify the metal before producing a product. 1

Iron ore can be mined at level 15 Mining providing 35 Mining experience. After an iron rock is mined, it will respawn in 5.4 seconds. Iron ore is used to smelt iron bars and can be smelted with coal to make steel bars. Smelting iron ore into iron bars has a 50% success rate, unless the player is wearing a ring of forging, using superheat item, or using the blast furnace.
