.Malachite is an ore of:a)Copperb)Magnesiumc)Calciumd)Both magnesium and calciumCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Malachite is a green copper carbonate hydroxide mineral with a chemical composition of Cu2(CO3)(OH)2. It was one of the first ores used to produce copper metal. It is of minor importance today as an ore of copper because it is usually found in small quantities and can be sold for higher prices for other types of use.

Answer

A i.e.cu because malachite is basic copper carbonate having formula copper carbonate copper di
hydroxide

Answer

Malachite is an ore of Copper.

Explanation:

What is an ore?
An ore is a naturally occurring substance from which a valuable metal or mineral can be extracted economically. Ores are typically mined from the earth's crust and then processed to extract the desired metal or mineral.

Malachite
Malachite is a green-colored mineral that is commonly found in copper deposits. It is a secondary mineral formed through the weathering and oxidation of primary copper minerals. Malachite has a distinctive green color and a characteristic fibrous or banded appearance. It is often used as an ornamental stone and is also a valuable source of copper.

Properties of Malachite
- Chemical Formula: Cu2CO3(OH)2
- Color: Green
- Lustre: Silky, Dull
- Streak: Light green
- Hardness: 3.5-4
- Cleavage: Perfect
- Fracture: Conchoidal
- Density: 3.6-4.05 g/cm3
- Crystal System: Monoclinic

Malachite as an Ore of Copper
Malachite is primarily composed of copper carbonate hydroxide (Cu2CO3(OH)2), which makes it a significant source of copper. It forms as a secondary mineral in the oxidized zones of copper ore deposits. When primary copper minerals are exposed to weathering and chemical reactions, they undergo various transformations, leading to the formation of malachite.

The presence of malachite in an area indicates the potential presence of copper deposits. Mining companies identify and extract malachite-rich ores to obtain copper. The ore is typically crushed and processed to separate the copper mineral from the gangue (unwanted rock and impurities). Various techniques such as flotation, smelting, and electrorefining are used to extract and purify the copper metal.

Conclusion
In conclusion, malachite is an ore of copper. It is a valuable source of copper due to its high copper content and is commonly found in copper deposits. Mining and processing of malachite-rich ores allow the extraction of copper for various industrial and technological applications.
