Which method is suitable for separation of ore from gangue, If ore is suitably soluble in some solvent.
Options:
Answer:
A
Solution:
Leaching is the suitable method. In leaching, the pulverized ore is treated with a suitable solvent that selectively dissolves the ore, forming a soluble complex, while the gangue remains insoluble and is filtered off. This process is effective when the ore is soluble and the impurities are not.
