Mauritania's Iron Ore Train | Amusing Planet

Some passengers dig small holes in the iron ore pile and build stoves, burning charcoal to make tea. After a 17-hour-long arduous journey, the train arrives at Nouadhibou, where the ore-blackened passengers climb down from their perches and unload their cargo. The train then continues on to the harbor to dump the 22,000 tons of ore.

Iron | Geoscience Australia

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.
