How Is Metal Made

Iron is a metal and it s found in rocks deep underground. Today about 98 percent of pig iron produced worldwide goes into the production of steel the most widely used metal or metal alloy in history.

Copper Production How Is Copper Made

The properties of pure metals can be improved by mixing them with other metals to make alloys.

How is metal made. A metal from greek μέταλλον métallon mine quarry metal is a material that when freshly prepared polished or fractured shows a lustrous appearance and conducts electricity and heat relatively well. Once the mix is complete it s put through a furnace to create a reaction that lowers the oxygen and carbon levels in the powder. The iron ore rocks are then.

Extracting an ore a deposit consisting usually of a huge amount of useless rock and smaller amounts of useful metals from a mine or quarry and then refining the ore to get the metals away from their oxides or other compounds into the pure form that we need. However alloys are when metals. Metal is made of metal it is an element and no combined substance can produce it also known as a natural resource.

To get to these rocks we have to use explosives and big machines to dig deep and take away the loose earth. The reduction in carbon and oxygen leaves the metal mix resembling a less delicious sponge cake. A metal in the form of a gravy boat made from stainless steel an alloy largely composed of iron carbon and chromium.

So metal is mined and refined rather than made. Pure metals like aluminium silver and copper come from the earth s crust. The process begins by pouring molten pig iron into steel furnaces where it is treated to remove any remaining impurities and to lower the carbon content to between 0 1 and 2 percent.

How metals are formed. Producing large quantities of a metal like iron aluminum or copper therefore involves two distinct operations. The metal ore is crushed and then mixed with another material usually carbon.

Caustic soda sodium hydroxide is used to dissolve the aluminum compounds found in the bauxite separating them from the impurities. It takes about 2 kg of bauxite to produce 0 5 kg of aluminum metal. They are found in ores solid materials called minerals usually occurring in rock from which the pure metal has to be extracted.

Depending on the composition of the bauxite ore relatively small amounts of other chemicals may be used in the extraction process. These metals like gold silver and platinum occur naturally in the earth s crust as small grains or as larger lumps of metal. Some metal elements do not combine easily with other elements.
