Question:
The process which involves the treatment of the ore with a suitable reagent so as to make it soluble but not impurities is called
The process which involves the treatment of the ore with a suitable reagent so as to make it soluble but not impurities is called
Show Hint
Remember that leaching is a selective dissolution process. The choice of the leaching reagent depends on the specific mineral to be extracted and the nature of the impurities present in the ore.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the definition of each given metallurgical process.
Froth flotation: A separation technique based on the difference in the wettability of mineral and gangue particles.
Roasting: Heating an ore in the presence of air to convert it to a metallic oxide or other compound.
Hydrometallurgy: The extraction of metals from their ores using aqueous solutions.
Leaching: The process of selectively dissolving a desired mineral from an ore using a suitable reagent, while the impurities remain insoluble.
Step 2: Match the description in the question with the correct process.
The question specifically describes the selective dissolution of the ore while leaving impurities undissolved. This is the definition of leaching. Final Answer: The final answer is $\boxed{Leaching}$
