Copper can be extracted from various minerals. The correct answer is:
(1) (B), (D), (E) only
Copper can be extracted from:
- (B) Malachite:
- Malachite is a green mineral that is a secondary copper ore. It is a copper carbonate hydroxide mineral, with the chemical formula Cu2(CO3)(OH)2. Malachite is well known for its striking green color, which varies from light green to dark green, often with banding or concentric rings. This mineral is a popular ornamental stone and has been used for centuries in jewelry, carvings, and other decorative items.
- (D) Copper glance:
- Copper glance, also known as chalcocite, is a mineral and an important ore of copper. It has the chemical composition Cu2S, meaning it is primarily composed of copper and sulfur. Copper glance is a dark gray to black mineral with a metallic luster and is often found in massive or granular form. It is one of the main copper ores and is typically associated with other copper minerals in copper-bearing deposits.
- (E) Cuprite:
- Cuprite is a mineral and a secondary ore of copper with the chemical formula Cu2O. It is composed of copper and oxygen, and it typically appears as deep red to brownish-red crystals or powdery masses. Cuprite gets its name from the Latin word "cuprum," which means copper, due to its high copper content.
Cryolite (option A) and calamine (option C) are not typically sources of copper extraction.
