Study on the improvement of the zinc pressure leaching
Aug 01, 2020· The zinc extraction can reach 96.7 after grinding the coarse particles 74 μm prior to leaching. The extraction of other metals are 84.7 , 81.7 and 81.4 for iron, gallium, and germanium, respectively. The total recovery of the two stage leaching is 98.2 , 90.0 , 86.3 and 87.8 for zinc, iron, gallium, and germanium, respectively.
