Aluminum is extracted from

Options

A. hematite
B. bauxite
C. calamine
D. magnetite

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks from which ore aluminum is extracted.

2. **Understand Aluminum as a Metal**: Recognize that aluminum is a metal, and metals are typically extracted from ores.

3. **Identify the Ore of Aluminum**: The ore from which aluminum is extracted is aluminum oxide, represented chemically as Al2O3.

4. **Name the Specific Ore**: The specific name of the ore from which aluminum is extracted is bauxite. Bauxite is primarily composed of aluminum oxide and is the principal source of aluminum.

5. **Describe Bauxite**: Bauxite is a sedimentary rock that contains a high percentage of aluminum. It is the main source of aluminum metal.

6. **Extraction Process**: Aluminum is extracted from bauxite through a process called the Bayer process, where bauxite is refined to obtain pure aluminum oxide (Al2O3).

7. **Electrolysis for Extraction**: After obtaining aluminum oxide, the extraction of aluminum metal is done through electrolysis, often using molten cryolite to lower the melting point and improve conductivity.

8. **Final Answer**: Therefore, aluminum is extracted from bauxite.

**Final Answer**: Aluminum is extracted from bauxite.
