Detailed explanation-1: -The various processes involved in extracting metals from their ores and refining them for use are referred to as metallurgy.

Detailed explanation-2: -Distillation: This method is used for the purification of metals which possess a low boiling point such as mercury and zinc. In this process, the impure metal is heated above its boiling point so that it can form vapours. The impurities do not vaporise and hence they are separated.

Detailed explanation-3: -Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.

Detailed explanation-4: -The branch of science and technology that studies the properties of metals and their production and purification is known as metallurgy. Naturally occurring solid inorganic substance is known as a mineral. Naturally occurring solid material from which valuable mineral or metal can be extracted is known as ore.
