How is copper extracted from low grade copper ores?

Explanation

To extract copper from low-grade copper ores, the following steps are involved:

### Step 1: Leaching
- **Process**: The low-grade copper ore is subjected to a process called hydrometallurgy, which involves leaching. In this step, the ore is treated with a suitable solvent (often an acidic solution) that dissolves the copper ions while leaving behind the impurities.
- **Chemical Reaction**: The general reaction can be represented as:
\[ \text{Cu ore} + \text{Acid} \rightarrow \text{Cu}^{2+} \text{ ions in solution} + \text{Impurities} \]
