Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of prod

Higher-grade metallic ores found in veins deep under the Earth’s surface can be profitably mined using underground methods, which tend to be more expensive. Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well.
Energy and Environmental Profile of the U.S. Mining
4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

It is so bizarre to me to think of mining for iron in a bog of all places. "Yeah, let's go somewhere marshy and wet to look for iron!" Sure, there isn't much oxygen to turn the iron into rust, but neither is there water flow to erode the rock and leave the iron (if indeed that is what happens when water flows over iron ore/iron-containing rock.)
