  • EFFECT OF LEAD NITRATE ON CYANIDATION OF

    This paper deals with the effect of the addition of lead nitrate and ultra-fine grinding on the cyanidation of an antimonial refractory gold and silver ore. The ...

  • Effect of oxygen and lead nitrate on the cyanidation of

    At high cyanide concentration, the rate of dissolution depends only on the oxygen concentration according to: (3) rate = 2 AD02 8-1 102 1 (4) Figure 3 illustrates the effect of oxygen and lead nitrate separately. The addition of 100 g/t lead nitrate yielded the best gold recovery (95.9%) and the lowest cyanide consumption (0.59 kg/t).
