Phosphorous is usually extracted from

Options

A. Phosphorite
B. Apatite
C. Chlorapatite
D. Triphylite

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks where phosphorus is usually extracted from.

2. **Analyze the Options**: The options provided are:
- Option 1: Phosphorite
- Option 2: Apatite
- Option 3: Chlorapatite
- Option 4: Triphalite

3. **Understanding Phosphorite**: Phosphorite is a type of sedimentary rock that contains a high concentration of phosphate minerals. It is often referred to as "rock phosphate" and is the primary source for phosphorus extraction.

4. **Evaluate Other Options**:
- **Apatite**: This is a group of phosphate minerals, which includes hydroxyapatite, fluoroapatite, and chloroapatite. While it is related to phosphorus, it is not the primary source for extraction.
- **Chlorapatite**: This is a specific type of apatite that forms in fluorodeficient environments and is found in certain geological formations. It is not a primary source for phosphorus extraction.
- **Triphalite**: This is a lithium iron phosphate mineral. It does not serve as a source for phosphorus extraction.

5. **Conclusion**: Based on the analysis, the correct answer is Option 1: Phosphorite, as it is the main source from which phosphorus is extracted.

**Final Answer**: Phosphorus is usually extracted from **Phosphorite**.
