Extraction of iron and its conversion into steel. IRON AND STEEL. This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. Extracting iron from iron ore using a Blast Furnace.
Iron ore, carbon (also called 'coke') and limestone are heated in a blast furnace. The carbon reacts with oxygen blasted into the furnace from the bottom to form carbon monoxide.
Refractory ore contains carbon and is heated to over 1000 degrees F, which removes sulfide and carbon. The resulting oxide ore is directed to the leaching circuit. Sulfide refractory ore that contains no carbon is oxidized in an autoclave to free gold from sulfide minerals, then it is sent to the leaching circuit.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Extracting copper from its ores. ... The cathode is either a strip of very pure copper which the new copper plates on to, or stainless steel which it has to be removed from later. ... The copper(II) sulphate solution has to be continuously purified to make up for this.
Steel is an alloy of iron and carbon and other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Iron is the base metal of steel.

Steel is much more than just purified iron. There are carbon atoms interspersed with the iron through a process of heating and cooling. This process changes the properties of the metal including the tendency for atoms to align in the same direction.
Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of ...
Gold can be purified to its most highly-refined state through the Wohlwill process, which was invented in 1874 by Emil Wohlwill. In this electrochemical process, impurities are removed from the ore by first melting it with chloroauric acid, which serves as an electrolyte, and then passing an ...
Some examples of ferrous metals would be mild steel, cast iron, high strength steel, and tool steels. Examples of non-ferrous metals would be copper, aluminum, magnesium, titanium, etc. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an …
