Estimation of Rh, Ru, and Ir leaching kinetics during the sulfuric acid pressure leaching of Ni–Cu matte as a function of temperature, pressure, and acid concentration

In order to develop an improved understanding of the leaching behaviour of base metals and platinum group metals in a high pressure sulfuric acid leaching system, bench scale batch tests were performed to evaluate the effects of temperature, pressure, acid concentration, and solid-to-liquid ratio on...
