Mining

Mining

Minerals are found in semi-pure form, or combined with many impurities and oxides

It is easy to extract some of them, such as iron and copper, from surface mines, and some are found in deep mines

Mining often causes harm to the health of miners and damages the environment, such as air pollution, river water and groundwater due to the

materials used to isolate the substance from impurities

Metal Benefit Techniques

To take advantage of the minerals, they must be shaped so that they take the shape we want, and there are two ways: machining and forming

Machining

Mechanisms are used to remove parts of the metal until it takes the desired flat, circular, cylindrical, or stripped shape. Screws or openings can also be made

Formation

FIRST

The metal is formed in the states of hardness and cold, by pulling it to turn from a thick mass into plates or wires, and the technique of converting to plates is called rolling and converting to wires by drawing

Secondly

Shaping the metal in the states of hardness and heat: the metal is heated to reddening and we shape it by hammering it with a heavy hammer. This technique is called blacksmithing
