1. Introduction
The majority of treatments developed or proposed over the years can be categorised as cyanide destruction and recovery technologies [10] and [11]. The most widely adopted cyanide destruction technologies ICG-001 alkaline chlorination process as follows [12] and [13]:equation(1)CN− + Cl2 → CNCl + Cl−equation(2)CNCl + 2OH− → CNO− + Cl− + H2Oequation(3)2CNO− + 3Cl2 + 6OH− → N2 + 2HCO3− + 6Cl− + 2H2O
