Thioureathiocyanate leaching system for gold ScienceDirect

Increasing the pH value does not affect the gold leaching rate significantly for the mixed lixiviant system. What is observed is the gold leaching rate for pH 1.5 is a little higher than that for pH 1.0 and 1.9. In the thiourea only solution, a high pH value is favorable for gold dissolution (Li and Miller, 2007).
