    2021-6-8 · At a pH of 9.39.5 CN-and HCN are in equilibrium with equal amounts of each present. At a pH of 11 over 99 of the cyanide remains in solution as CN- while at pH 7 over 99 of the cyanide will exist as HCN. Although HCN is highly soluble in water its solubility decreases with increased temperature and under highly saline conditions.

  • Gold cyanidation using hydrogen peroxideScienceDirect

    1999-4-1 · The gold cyanidation rate in the presence of hydrogen peroxide is highly sensitive to pH. Nevertheless at relatively low pH values cyanidation rates are higher than those obtained in conventional cyanidation. In fact the cyanidation rate can be doubled by adding small amounts of H 2 O 2 (0.015 M) to conventional cyanidation at pH 10.
