Thiourea–thiocyanate 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).
