Decomposition of Cyanide from Gold Leaching Tailingsby Using Hindawi

As explained above the best conditions for decomposition of cyanide from leach tailings are first treated in g/L Na 2 S 2 O 5 at pH 10 for 3 hours and then 2 mL/L H 2 O 2 is added to the tailings at pH 9 for 4 4 Conclusions The decomposition of cyanide increased as the alkalinity of the solution and tailings increased in the presence of g/L Na 2 S 2 O 5
