Forms of Iron Minerals, Ores, and Rocks Iron occurs mainly in ironoxide ores. Some ores are a mixture of minerals rich in iron. Other iron ores are less rich and have a large number of impurities. The most important iron oreforming minerals are: • Magnetite Magnetite (Fe3O4) forms magnetic black iron ore. There are large deposits of

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.

Smelting: roasting rock at a temperature greater than 900 o C. This causes it to segregate into layers. The valuable minerals are then extracted. This requires a lot of energy. Extracting metal from rock is so energyintensive that it's much better to recycle. We use over 80 billion aluminum cans each year.

After harvesting, the biomass is typically dried and incinerated to produce a "bioore" prior to the product recovery process (Chaney et al., 1998, van der Ent et al., 2021, Vaughan et al., 2017). At first, the product recovery process has focused on crude metal extraction from the 'bioore' using pyrometallurgy (Chaney et al., 2007).

8. Check the mining pan periodically to see if the gold is extracted. Pull the mining pan out of the water and look at the pieces that remain in the pan. Pick out any gold pieces and place them in a separate container. Continue to shake the mining pan in the water until you've picked out all of the gold pieces.

An ore is a type of rock containing compounds from which metals can be extracted. Ores are typically metal oxides or a compound of a metal that can be converted to an oxide. For example, the main aluminium ore is called bauxite which is aluminium oxide (Al 2 O 3). The metal is removed from the oxide in a process called reduction.

Mild steel. Mild steel is iron containing up to about % of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things nails, wire, car bodies, ship building, girders and bridges amongst others.
