Mineral deposit - Iron deposits | Britannica

Mineral deposit - Mineral deposit - Iron deposits: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world's great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded iron formations (BIFs), so ...

Iron ore - Wikipedia

The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist. The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market and the energy cost required to do so. Mining iron ore is a high ...

Massive deposits of titaniferous iron ores are known in a number of countries. Their relative commercial value depends not only on the titanium content but on the liberation size of the titanium mineral. Pre­ sently ilmenite is being won from titaniferous iron ore deposits in New York, Canada, Finland, and Norway.
