The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the mostused metal by both tonnage and purpose.

LAUNCESTON, Oct 22 – With China's antipollution restrictions starting to take effect, one of the conventional market wisdoms is that this will boost demand for highgrade iron ore. The logic is sound: If steel mills are restricted as to how much they can pollute, they will use the best possible quality iron ore in order to maximise the amount of steel produced relative to the energy consumed.

Air pollution from the steel sector is the result of emissions of particulate matter containing minerals (iron, iron oxide), metals (cadmium, lead, chromium, nickel, zinc, copper and arsenic) and other pollutants (polycyclic aromatic hydrocarbons, nitrogen oxides and sulphur dioxide).
Iron is considered to be one of the most unstable minerals in our ground water supply. As water percolates through the ground strata it dissolves the iron from the iron ore deposits as ferrous bicarbonate [Fe (HCO3)2 ], sometimes referred to as "clear water iron." When iron is dissolved in water you cannot see it.

Mining and processing. If the ore contains less than 60 percent iron, it is usually beneficiated to an ironore concentrate typically containing greater than 60 percent iron. This is done by separating the iron minerals from the valueless minerals, usually by magnetic, gravity, or froth floatation.
Lead Pollution. Because the material that is mined for is surrounded by other ore and rock, mining creates large amounts of mineral waste in the form of waste rock and tailings. Waste rock consists of all of the earth surrounding the ore that must be removed in order .
