Sodium sulfate activation mechanism on co-sulfating roasting to nickel-copper sulfide concentrate in metal extractions, microtopography and kinetics

Autor: Shuai Wang, Shaohua Luo, Qian Xu, Wenning Mu, Yuchun Zhai, Haixia Xin, Fuhui Cui

Publikováno v: Minerals Engineering. 123:104-116

Due to the complexity of occurrence of valuable metals and high content of alkali gangue in nickel-copper sulfide concentrate, traditional pyrometallurgical processing is not suitable. In this work, a two-stage co-sulfating roasting process was used

Synchronous extractions of nickel, copper, and cobalt by selective chlorinating roasting and water leaching to low-grade nickel-copper matte

Autor: Zhai Yuchun, Fuhui Cui, Hong-tao Shen, Shuai Wang, Haixia Xin, Qian Xu, Shaohua Luo, Wenning Mu

Publikováno v: Separation and Purification Technology. 195:149-162

Due to the low recovery of valuable metals and the great loss of Co in the smelting process, the traditional pyrometallurgical process suffers to treat low nickel-copper matte efficiently. This work focused on a novel and controllable two-stage chlor
