e traction of gold by leaching process

Explain the leaching process of silver and gold using .Answer. The addition of gold or silver to an alkaline sodium cyanide solution will cause the metals to react with the cyanide and dissolve them into the solution. The process is called cyanidation or leaching.The cyanide process of gold extraction involves .The cyanide process of gold extraction involves leaching out gold from its ore with CN– in the presence of Q in water to form R.
