Extractive metallurgy - Wikipedia

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...

Occurrence of Metals - Study Material for IIT JEE | askIITians

The process of extracting metals from ores is known as Smelting which was discovered around 6500 BC. Alloys. It is a mixture of two or more elements in which the major component is metal. Alloys are made to obtain desirable characteristics. The basic idea to make alloy is to make metal less brittle, hard and more resistant to corrosion.
