    Cyanidation of gold ores containing copper, silver, lead

    Cyanidation tests on two ore samples from two different gold deposits are reported. The first sample contained 10.5 ppm gold with high arsenic and antimony. The second sample had a low gold content (2.5 ppm) but a high silver content (160 ppm).

    The gold extraction was only 69.6% even after extending the pre treatment by 16 h at pH 10.5, 16 ppm oxygen and with 250 g/t lead nitrate. This poor performance is attributed to the higher dissolution of antimony during leaching (134 ppm). The formation of stibnate retards gold leaching.
