Iron Ore Statistics and Information - usgs.gov
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.

Mining yield - UniWiki - Eve University
Mining yield is the rate at which miners mine ore, ice, or gas.As all mining modules mine a certain volume of ore/ice/gas in a given time, the amount of ore/ice/gas mined therefore depends on this mining rate (often quoted in m 3 per minute) and on the volume of the ore/ice/gas (m 3) being mined.
