उत्तर

MacArthur-Forrest process is used for the extraction of silver.

Explanation:

The MacArthur-Forrest process is used to extract silver from its low-grade ores. In this method, the ore is treated with a dilute sodium cyanide (NaCN) solution in the presence of air, which dissolves silver as a complex.

\[\ce{Ag + NaCN + O2 + H2O -> Na[Ag(CN)1] + NaOH}\]
