Answer 1

Metallurgy is defined as a process that is used for the extraction of metals in their pure form. The compounds of metals mixed with soil, limestone, sand, and rocks are known as minerals. Metals are commercially extracted from minerals at low cost and minimum effort. These minerals are known as ores. A substance which is added to the charge in the furnace to remove the gangue (impurities) is known as flux. Metallurgy deals with the process of purification of metals and the formation of alloys.

Answer 2

Metallurgy :- It is a process through which ore are extracted from their metal this is known as

metallurgy.

☆ Methods through which ore are extracted from their metals are :-

• Ore dressing - It is an process in which removing of unwanted substance from the ore is involve.
• Froth Flotation - The unwanted substance float on water and thus it can be easily separated.
• Leaching - Using the chemical properties of minerals and gangue.
• Roasting - ore is heated in presence of air to obtain metal oxide.
• Calcination - Heating substance to remove moisture and volatile impurities and convert carbonates ore into oxides.
