The process that involves the removal of sulphur from the ores is :
Show Hint
- Roasting
- Smelting
- Leaching
- Refining
The Correct Option is A
Solution and Explanation
Smelting reduces the metal oxide to the metal with carbon in a furnace, leaching dissolves the ore in a chemical reagent (e.g. bauxite in NaOH), and refining purifies the crude metal.
Answer: (1) Roasting

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
