Cyanide Free Gold Leaching Alternative

 · Cyanide (CN –) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H 2 O) to form a gold cyanide complex (Na [Au(CN) 2] ) and sodium hydroxide (NaOH). The chemical reaction dubbed the "Elsner Equation", named after its discoverer, is shown below: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na[Au(CN) 2] + 4 NaOH. Cyanide ...
