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

Premature babies have less of an iron reserve – and need supplements – because they don't get sufficient iron stores from Mom in the last trimester. The earlier a premature baby is born and the faster that baby is growing, the sooner she'll need iron supplementation.)
The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite. Commercially, iron is produced in a blast furnace by heating haematite or magnetite with coke (carbon) and limestone (calcium carbonate).

Another lithium ore is spodumene, which like petalite is a lithium aluminium silicate, and there is a large deposit of this ore in South Dakota. World production of lithium compounds is around 40 000 tonnes a year and reserves are estimated to be around 7 million tonnes. Industrial production of the metal itself is reported to be about 7500 tonnes a year, and this is produced by the ...
"Recoverable reserve" – This term refers to the amount of the reserve base that might reasonably be expected to be actually mined and used. The "recoverability" factor of coal depends on a number of factors such as the method of coal mining used, but in general is considered to be about 50% of the reserve base.
