Sedimentary deposits are represented by the lean siliceous ore of the iron formation, as at Moose Mountain and Temagami, Ontario, and by magnetic black sand found on the north shore of the St. Lawrence; both of these may prove to be important. They can be concentrated magnetically, and this is being done on a large scale with the taconite of Minnesota, the ore carrying only 25% of iron.

Iron ore deposits not minable? I have found numerous iron ore streaks in caves (the brownish red streaks that have clearly been worked before).

Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and a good supply of oxygen (provided by a bellows or blower).
