“…If all of the zinc in the MOVs is leached, the total zinc concentration will be 0.11 M in the leaching solution because the mole ratio of H 2 SO 4 to zinc ions is 1. The experimental results are almost consistent with the fundamental analysis [21]. The effect on zinc extraction was studied by varying the initial H2SO4 concentration from 0.05 M to 1 M while the leaching temperature was kept constant at 333 K. The results are shown Figure 4.…”

“…The hydrometallurgical process is more economically attractive, as the pyrometallurgical method suffers from high energy consumption and capital investment. Acids [4,5], sodium hydroxide [6,7], and ammoniacal solutions are often used as leaching agents [8,9].…”
