In fact, by using a thiourea leaching solution of 4% v/v at pH = 1, obtained by adding H 2 SO 4, only 30% of the gold content was recovered and the resulting leachate contained more than 50 g/L of iron. As in the cyanidation tests, the phenomena of loosing gold already dissolved was also observed during the thiourea leaching experiment.
