Question

Hydro-metallurgical process of extraction of metals is based on

hydrolysis

dehydrogenation

dehydration

complex formation

Answer

complex formation

Explanation

Solution

Hydrometallurgical process is for the ores of $Ag$ and $Au$ It is based on complex formation e.g., $Ag_{2}S+4kCN \to 2Na[Ag(CN)_{2}]+Na_{2}S$ $2Na[Ag(CN)_{2}]+Zn \to Na_{2} [Zn(CN)_{4}]+2AG$
