is relatively low, the electrogenerative leaching rates are predicted to be proportional to 6/7, 4/5, 2/3 and 2/3 order of ferric ion for nickel concentrate, chalcopyrite concentrate, sphalerite and galena... (CuFeS2, Cu 22.3%), sphalerite (Zn 61.39%), galena (Pb 60.1%), were taken as the anodic materials respectively. An ion-selective membrane connected the separated anolyte and catholyte compartments so......
(GB25466-2010). The wastewater without treatment affected galena and sphalerite electrochemical behaviors greatly, after treatment by the technology, the effects disappeared, which proved the reliability......

sulfidation roasting. EPMA analysis results demonstrated that surface of the obtained massicot was smooth, but surface of the artificial galena was rough and even porous. Content of oxygen decreased, whereas... 90% of lead oxide to transform into lead sulfide. The second step roasting was carried out at 750 °C to synthesize perfectly crystalline galena, which is readily floated in a conventional flotation......
