The landmark court case focused North America, and the world, on the issue of asbestos in water. For decades, the mining giant had been dumping iron-ore tailings into Lake Superior. During the investigation into the Reserve case, it was revealed that a litre of water in nearby Duluth, Minnesota had as many as 644 million amphibole fibres in it.

When the earth coalesced 4.6 billion years ago, the heavy iron concentrated in the core. It stayed molten from the heat of compression and radioactive decay until 1-1.5 billion years ago, when the inner core crystallized and the iron (and about 4-8% nickel) "froze." The outer core or iron, nickel, and a few lighter elements has remained molten.

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
