INTRODUCTION
Metal such as iron, copper and aluminum all start out as ore which must be processed to produce the actual metal. This is done in the refinery. Metal is processed from a natural solid mineral ore found beneath the earth called iron-ore. In its natural state iron-ore contains many impurities that is removed through smelting.
After iron, copper and aluminum have been refined, they can be mechanically shaped to form a particular product. Different metals may also be mixed to produce alloys.
Meaning of Metals
Metals are materials used in producing equipment used in everyday life. The most common metals are iron, aluminum, tin, etc. Metals are usually solid but a few of them occur in liquid or powder form. They are made from raw forms called ores. Ores are usually dug from the earth or obtained from rocks.
Metals come in different forms such as rods, tubes, plates, wires, bars, and liquid.
Ferrous metals contain iron and are magnetic, while non-ferrous metals do not contain iron and are non-magnetic.You are viewing an excerpt of this lesson. Subscribing to the subject will give you access to the following:
