Iron Ore Statistics and Information

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 steel industries.

Steel production environmental impact

Iron doesn't occur naturally. Being highly reactive, it combines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine. The principal iron ores are hematite (Fe2O3) and magnetite (Fe3O4). Most iron ore is extracted through opencast mines.

When mining operations cease, and the water pumps are dismantled, these large open pits may slowly fill with water, forming lakes.

We Need To Talk About Mining: Death, Dangers Prevention

Cave-ins, explosions, toxic air, and extreme temperatures are some of the most perilous hazards observed to take place in underground mining. Valuable minerals are found all over the world. And most often the only way to get to them is by mining into the earth's ground. Not an easy or riskless feat to achieve even in the simplest of locations.

iron processing

Most iron ores are extracted by surface mining. Some underground mines do exist, but, wherever possible, surface mining is preferred because it is cheaper. Lumps and fines Crushing As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch).

How can mining become more environmentally sustainable?

ARD can pollute surface and groundwater with acidity and dissolved metals, which can adversely affect aquatic organisms and water users downstream. A number of strategies are used to predict, prevent, and mitigate ARD at mine sites, and are described in further detail here. Restoring environmental function at mine sites

Acid Mine Drainage

When the mining process exposes the sulfides to water and air, together they react to form sulfuric acid. This acid can dissolve other harmful metals and metalloids (like arsenic) from the surrounding rock. Acid mine drainage can be released anywhere on the mine where sulfides are exposed to air and water — including waste rock piles
