Abstract:Wet recycling method was utilized for recycling manganese from waste Zn-Mn batteries to obtain MnCO3. It was indicated that soaking time, the concentration and volume of acid all have great effects on the yield of MnCO3. The productivity of MnCO3 can reach 64.65%, when the concentration of HCl acid is 5mol/L, and with a volume of 40ml, under 180min soaking time. The productivity of MnCO3 can also reach 63.36%, when the concentration of HNO3 is 6mol/L, with 60ml volume by soaking for 80min. Furthermore, LiMn2O4… Show more
