Roasting is generally carried out in _____mineral.

Answer

**Step-by-Step Solution:**

1. **Understanding Roasting**: Roasting is a metallurgical process that involves heating metal sulfides in the presence of oxygen. This process helps in converting metal sulfides into metal oxides.

2. **Chemical Reaction**: The general reaction for roasting can be represented as:
\[ \text{Metal Sulfide} + \text{O}_2 \rightarrow \text{Metal Oxide} + \text{SO}_2 \]
Here, the metal sulfide reacts with oxygen to produce a metal oxide and sulfur dioxide (SO₂).

3. **Identifying the Type of Ore**: The question specifically asks about the type of mineral ore in which roasting is generally carried out. Since roasting involves the conversion of metal sulfides, it is typically associated with sulfide ores.

4. **Conclusion**: Therefore, roasting is generally carried out in **sulfide** minerals.

**Final Answer**: Roasting is generally carried out in **sulfide** mineral.
