Zhu, Huihui and Yu, Ranbo and Deng, Jinxia and Chen, Jun and Xing, Xianran (2012) Direct preparation of ferrite magnetic material from Jinchuan nickel sulfide concentrate by acid leaching. International Journal of Materials Research, 103 (8). pp. 998-1003. ISSN 1862-5282

Abstract

A preparation route of ferrite magnetic material by leaching of Jinchuan nickel sulfide concentrates in hydrochloric acid was developed. Pre-roasting of the concentrates could significantly improve the leaching efficiency of nickel. X-ray diffraction measurements, thermogravimetric, and differential thermal analyses were used to determine the phase transition after pre-roasting. The leaching could extract almost 100% nickel and 89% iron. The present process involved pre-roast of nickel sulfide concentrate, hydrochloric acid leaching at ambient pressure, solid -liquid separation, coprecipitation, and calcination. The nickel ferrite doped with Cu2+ and Mg2+ could be obtained by co-precipitation and calcination. Further study confirmed that ferrite products were of spinel structure and exhibit good ferromagnetism.
