How is silver extracted from argentite ore?

Argentite ore is A g 2 S. It is leached with dilute NaCN solution in presence of air. A g 2 S + 2 N a C N → N a 2 S + + 2 A g C N ↓ A g C N + N a C N → N a [A g (C N) 2 ] or 4 A g + 8 C N − + 2 H 2 O + O 2 → [A g (C N) 2 ] − + 4 O H − From soluble complex, silver is displaced by zinc 2 [A g (C N) 2 ] − + Z n → [Z n (C N) 4 ] 2 − + 2 A g Zinc can displace A g as Z n is more active than A g.
