Bessemerisation is carried out for
(i) Fe (ii) Cu (iii) AI (iv) silver

Options

A. i,ii
B. ii,iii
C. iii,iv
D. i,iii

Explanation

To determine for which metals Bessemerisation is carried out, we need to understand the process itself and the metals involved. Let's analyze the options provided:

### Step-by-Step Solution:

1. **Understanding Bessemerisation**:
- Bessemerisation is a metallurgical process used primarily for the extraction of metals from their ores, particularly for the production of steel from iron and for the recovery of copper from its matte.

2. **Identifying the Metals**:
- The options given are:
- (i) Fe (Iron)
- (ii) Cu (Copper)
- (iii) Al (Aluminium)
- (iv) Silver

3. **Analyzing Each Metal**:
- **(i) Fe (Iron)**:
- Bessemerisation is indeed used for iron to produce steel. The process involves oxidizing impurities in molten iron, which forms slag that can be removed.
- **(ii) Cu (Copper)**:
- Bessemerisation is also used for copper, specifically for recovering it from copper matte (which contains Cu2S and FeS). The process oxidizes the sulfide to produce blister copper.
- **(iii) Al (Aluminium)**:
- Bessemerisation is not used for aluminium. Aluminium is extracted through electrolysis and does not undergo this process.
- **(iv) Silver**:
- Bessemerisation is not applicable for silver extraction. Silver is typically extracted through other methods such as cyanidation or smelting.

4. **Conclusion**:
- Based on the analysis, Bessemerisation is carried out for:
- (i) Fe (Iron)
- (ii) Cu (Copper)

### Final Answer:
Bessemerisation is carried out for (i) Fe and (ii) Cu.
