Thiocyanate Hydrometallurgy For the Recovery of Gold Part II: The Leaching Kinetics
, 2012 Acid thiocyanate leaching of gold was investigated in the presence of ferric sulfate as an oxidant. According to leaching kinetic studies the initial rate of gold leaching is slow, and not significantly dependent on thiocyanate (0.05-0.2 M) and ferric (0.
