| Abstract: | A zinc smelting residue contains silver(360 g/t).The form of silver in the acid leaching residue is relative complex,and most of silver is packaged in jarosites.The acid leaching-flotation process is examined for the acid residue.The experimental results show that the silver floation concentrate grade reaches 3 201 g/t,and the recovery of silver is 82.58%. |
