The element which is recovered from electrolyte process is `:`

Options

A. iron
B. lead
C. aluminium
D. zinc

Answer

To solve the question about which element is recovered from the electrolytic process, we can follow these steps:

### Step 1: Identify the Electrolytic Process
The electrolytic process is a method used to extract metals from their ores through electrolysis. In this process, an electric current is passed through a solution or molten substance to cause a chemical change.

**Hint:** Look for the definition and purpose of the electrolytic process in metallurgy.

### Step 2: Recognize the Ore Used
In the context of the question, the ore mentioned is bauxite, which has the chemical formula Al2O3·2H2O. Bauxite is primarily composed of aluminum oxide.

**Hint:** Identify the ore being used in the electrolytic process and its chemical composition.

### Step 3: Understand the Electrolytic Setup
In the electrolytic cell, there are two electrodes: the anode and the cathode. The anode is typically made of graphite, while the cathode is where the metal is deposited.

**Hint:** Remember the roles of the anode and cathode in electrolysis.

### Step 4: Determine the Reactions at Each Electrode
At the anode, oxidation occurs, where carbon reacts with oxygen to produce carbon dioxide and electrons. The reaction can be represented as:
\[ \text{C} + 2\text{O}^{2-} \rightarrow \text{CO}_2 + 4\text{e}^- \]

At the cathode, reduction occurs, where aluminum ions gain electrons to form aluminum metal:
\[ 2\text{Al}^{3+} + 6\text{e}^- \rightarrow 2\text{Al} \]

**Hint:** Focus on the oxidation and reduction reactions occurring at the respective electrodes.

### Step 5: Identify the Metal Produced
From the reduction reaction at the cathode, we can see that aluminum (Al) is produced as a result of the electrolysis of aluminum oxide.

**Hint:** Look for the final product formed at the cathode during the electrolysis.

### Conclusion
Based on the above steps, the element that is recovered from the electrolytic process is **aluminum**.

### Final Answer
The element which is recovered from the electrolytic process is **aluminum** (option number 3).
