  • What are the main factors that lead to high cyanide

    All Answers ( 7) The excess use of cyanide will increase its consumption because of the formation of cyano complexes from impurities. Furthermore, the decrease in cyanide concentration decreases cyanide consumption as well because 2 g/L cyanide solution is enough to dissolve gold present in ores.
