Metallurgy is the art of working metals, comprehending the whole process of separating them from other matters in the ore, smelting, refining, and parting them; sometimes, in a narrower sense, only the process of extracting metals from their ores.
Metallurgy is a domain of Material Science and Material Engineering.
It is a study of the physical and chemical behavior of metallic elements and their mixtures, called alloys.
Metallurgists study the microscopic mechanisms that cause a metal or alloy to behave in the way that it does, the changes that occur at the atomic level, that affect the metal's (or alloy's) macroscopic properties.
The various processes involved in the extraction of metals from their ores and refining are known as metallurgy.
The compounds of various metals mixed with impurities and found in nature are called minerals.
The naturally occurring metals from which metal can be extracted profitably and conveniently are called ores.
