1980; Wild et al. ed solutions for testing.A process for the removal of cyanide and other impurities from an aqueous solution is disclosed. The process comprises adding copper ion and ferrous ion as reagents to the solution at a pH of about 4 to 8 with a ratio of copper to cyanide in the range of 3:1 to 10:1 by weight and with a ratio of iron to copper of at least 0.3:1 by weight.Other cyanide destruction methods showing similar effectiveness (alkaline chlorination and hydrogen peroxide) do not offer environmental benefits over the INCO method (see FEIS,
