Web22 jul. 2016 · The leaching kinetics of zinc from zinc oxide-based metal oxide varistors (MOVs) was investigated in H2SO4 at atmospheric pressure. Kinetics experiments were carried out at various agitation speeds, particle sizes, initial H2SO4 concentrations, and reaction temperatures. It was determined that the leaching rate of zinc was independent … WebDuring the leaching process, Ni, Co, and Al, which had been reduced to metal form, were soluble in acid solution, except for the metal oxides. The leaching process carried out using citric acid in the absence of H 2 O 2 as a reducing agent produced a relatively low value of 34.8, 47.15, and 86.75% for Ni, Co, and Al, respectively.
