Question

Define
(i) Mineral
(ii) Ore
(iii) Gangue

Answer 1

Hint: Metallurgy is a branch of materials science and engineering that studies the physical and chemical properties of metallic elements, intermetallic compounds, and alloy mixtures. Metallurgy refers to both the science and the technology of metals, i.e., how science is applied to the production of metals and the engineering of metal components used in consumer and industrial products.

Complete answer:
Mineral:
A mineral is a naturally occurring inorganic solid having a crystalline structure and a specific chemical makeup. Mineral elements, either alone or in a variety of combinations known as compounds, make up the earth. A mineral is made up of a single element or combination. A mineral is a naturally occurring inorganic element with a specific chemical composition and atomic structure.
Examples- Alums \[{{K}_{2}}S{{O}_{4}}.A{{l}_{2}}{{(S{{O}_{4}})}_{3}}.24{{H}_{2}}O\]
Ore:
Ores are a collection of minerals that have been processed to yield an industrial mineral or chemically treated to yield one or more metals. Typically, steel, aluminum, chromium, zinc, mercury, manganese, tungsten, and some copper ores are treated for only one element. Although not all minerals are called ores, all ores are minerals.
Examples: \[A{{l}_{2}}{{O}_{3}}.2{{H}_{2}}O~\]- Bauxite (Ore of Aluminium)
Gangue:
A gangue is an undesirable component or contaminant that surrounds the mineral in an ore deposit, such as sand, rock, or any other material, according to chemistry. This substance is highly popular in the mining industry. The procedure of removing gangue from mineral is referred to as mineral dressing, mineral processing, or ore dressing.

Note:
Chemical metallurgy and physical metallurgy are the two major categories that make up the science of metallurgy. Chemical metallurgy is primarily concerned with metal reduction and oxidation, as well as metal chemical properties. Mineral processing, metal extraction, thermodynamics, electrochemistry, and chemical deterioration are all topics covered in chemical metallurgy (corrosion).
