What is cyanide and why do we need cyanide-free gold leaching process? 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 …
