​

Answer 1

Explanation:

A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. ... In geology and mineralogy, the term "mineral" is usually reserved for mineral species: crystalline compounds with a fairly well-defined chemical composition and a specific crystal structure.

Answer 2

${ \bold{ \text{ \underline{Minerals:-}}}}$

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.

EXAMPLES:-

• Iron ore.
• Silver.
• Gold.
• Cobalt.
• Bauxite.
• Lithium.
• Zinc.
• Potash.

${ \bold{ \text{ \underline{ \underline{Types:-}}}}}$

Minerals are divided into 2 types Metallic and Non - Metallic minerals.

Metallic Minerals

Metallic minerals exhibit lustre in their appearance and consist of metals in their chemical composition.

Examples :-

• Manganese
• iron ore
• and bauxite .

Non-metallic minerals

Non-metallic minerals are minerals which either show a non-metallic lustre or shine in their appearance. Extractable metals are not present in their chemical composition.

• Limestone
• gypsum
• and mica .

✒Bauxite ore mostly exists in deeply weathered rocks. Volcanic rocks contain bauxite deposits in some regions.

✒Iron metal extracted from iron ore. It never exists in pure form and has to be extracted from iron ore by eliminating the impurities.

✒Gold is the oldest and most precious element to be known.

✒Manganese ore is a silvery brittle or grey-white metallic ore occurs in many forms and found worldwide.
