Test: Mineral And Power Resources - 1 - UPSC MCQ

Yes the correct answer is B as all the other properties like colour, hardness,density( weight) are the physical properties they define the physical appearance of the minerals....But presence of sulphides is a chemical property of the minerals as it defines it's chemical composition....

High-grade ore contains a large concentration of the desired mineral. Low-grade ore has a smaller concentration.

The largest concentration of monazite sand is on the Kerala coast.

Answer:
Metal can be obtained in raw form from metallic minerals. Here is a detailed explanation:
Metallic Minerals:
- Metallic minerals are minerals that contain metals in their raw form.
- These minerals are typically found in the earth's crust and can be extracted through various mining methods.
- Examples of metallic minerals include iron ore, copper, gold, silver, and aluminum.
- These minerals are valuable resources as they are used in various industrial processes and for the production of metals and alloys.
Quarried Minerals:
- Quarried minerals refer to minerals or rocks that are extracted from quarries, which are open-pit mines.
- While quarries can produce minerals such as limestone, granite, and marble, these minerals are not in their raw form and do not contain metals.
Drilled Minerals:
- Drilled minerals refer to minerals that are extracted through drilling methods, such as oil drilling or mining of mineral deposits.
- While drilling can be used to extract minerals, the minerals obtained through drilling are not necessarily in their raw form and may not contain metals.
Non-metallic Minerals:
- Non-metallic minerals are minerals that do not contain metals in their raw form.
- Examples of non-metallic minerals include limestone, gypsum, clay, and quartz.
- These minerals are used in various industries such as construction, ceramics, and glass manufacturing.
Therefore, the correct answer is A: Metallic minerals. These minerals contain metals in their raw form and can be extracted for further processing and use.

Metals : Metals are the elements which can easily loose electrons and forms cations.

Properties of metals :

• They are lustrous (shine).
• They are malleable and ductile (flexible).
• They conduct heat and electricity.
• The metallic oxides are basic in nature.
• They form cations in an aqueous solution.

Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.

Properties of non-metals :

• They are non-lustrous.
• They are brittle and hard in nature.
• They do not conduct heat and electricity.
• The non-metallic oxides are acidic in nature.
• They form anions in an aqueous solution.

Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.
