Which of the following metals is obtained by leaching its ore with dilute cyanide solution?
Silver
Titanium
Vanadium
Zinc
Silver is obtained by leaching its ore (Argentite, Ag2S or horn silver, AgCl) with dilute cyanide solution by which it is extracted in the form of a soluble complex.
Silver is recovered from solution of sodium dicyanoargentate by treating it with zinc scrap.
Therefore, the option number (1) is correct.
