Nickel leaching from low-grade nickel matte using aqueous ferric chloride solutionZhi-Qiang Ning,Hong-Wei Xie,Qiu-Shi Song,Hua-Yi Yin,Yu-Chun ZhaiSchool of Metallurgy,Northeastern University摘 要:Nickel leaching from low-grade nickel matte(LGNM) using aqueous ferric chloride solution was studied.The influence of factors such as leaching temperature......
years, numerous studies on the leaching of Ni-Cu matte have been reported. The leaching behaviors of nickel-copper matte at atmospheric pressure were studied[3-6]. The studies on high pressure leaching of nickel-copper matte were also conducted[7-8]. Especially, a semi-empirical mathematical model for the acid-oxygen pressure leaching of Ni-Cu matte has been developed for the improvement......
