2) metals are still used for most of machines, structures and instruments.
Most metals are usually found in nature as minerals or ores, where they exist in chemical combinations with other substances.
Ores are usually mined and passed to the metallurgist for refining and purification.
The ores are treated by fire or chemically by the process called smelting.
But pure metals are comparatively seldom used because they are rather expensive and their strength is generally insufficient for the purposes of to-day.
Alloys are obtained by adding various metals or non-metals to the main metallic element.
