Question
The process of bringing the metal or its ore into solution by the action of a suitable chemical reagent followed by extraction of the metal either by electrolysis or by a suitable precipitating agent i.e. more electropositive metal is called :
Options
A.electrometallurgy
B.hydrometallurgy
C.electro-refining
D.zone refining.
Solution
A hydrometallurgical process for the extraction of metals from ores, concentrates, or secondary materials essentially contains three basic steps-dissolution of the valuable metal in the aqueous solution (leaching) purification of leach solution and subsequent recovery of metal from the purified solutions either by electrolysis or by adding some electropositive metal to it.
