and pose a potential environmental threat because of their considerable amounts of entrained heavy metals(mainly lead). Most ZLRs have not been properly treated and the valuable metals in them have not yet been effectively recovered. Herein, the deep cleaning of a ZLR and recovery of valuable metals via a hydrometallurgical route were investigated. The cleaning process consists of two essential......
Trans. Nonferrous Met. Soc. China 27(2017) 1180-1187 Recovery of valuable metals from zinc leaching residue by sulfate roasting and water leaching Guo-min JIANG1,3, Bing PENG1,2, Yan-jie LIANG1,2, Li... and water leaching was employed to recover the valuable metals from ZLR. The ZLR was initially roasted with ferric sulfate at 640 °C for 1 h with ferric sulfate/zinc ferrite mole ratio of 1.2.......
