Question

Which among the following is a metallic mineral?
1. Sandstone
2. Bauxite
3. Mica
4. Potash

Answer 1

Correct Answer - Option 2 : Bauxite

The correct answer is Bauxite.

​​ 

• Bauxite is a sedimentary rock that has a relatively high content of aluminium. It is the smallest source in the world of iron and gallium.
• In lustre, bauxite appears dull and is reddish-brown, white, or tan in colour. Bauxite was discovered by the French geologist Pierre Berthier in 1821, near the village of Les Baux in Provence, southern France.
• The largest bauxite producer in Australia, followed by China. Increased recycling of aluminium, which has the benefit of reducing the expense of electrical energy in the manufacture of aluminium, would greatly increase the stocks of bauxite in the world.

• The minerals which contain one or more metals are metallic minerals.
• They are usually present as mineral deposits and are a strong conductor of electricity and heat, such as iron, copper, gold, bauxite, manganese, etc.
• In nature, they are malleable and ductile, so they can easily be pounded into thin sheets or stretched into wires to create new items.

• Sandstone is a sedimentary rock consisting of grains of mineral, rock, or organic material that are sand-sized.
• Mica is a mineral name given to a group of physically and chemically related minerals.
• Potash contains various salts extracted and manufactured that contain water-soluble potassium.
