As an important strategic metal,nickel is widely used in ternary power battery and other industries. In the con-text of the strong demand for nickel raw materials in the development of high-nickelization of ternary power batteries,with the increasing shortage of high-quality nickel sulfide ore resources,the realization of green and efficient extraction of laterite nickel ore resources can open up a new nickel industry layout,and has positive significance for promoting the sustainable development of new energy industry. Pyrometallurgical process has the advantages of short flow and strong applicability to raw materials,and has gradually become the mainstream treatment process of laterite nickel ore. The production of nickel matte by reduction smelting and reduction sulfide smelting is briefly introduced,and their advantages and disadvantages are analyzed. The production of nickel matte by oxygen rich side-blowing reduction sulfide smelting is emphasized,and the fea-sibility of green and efficient extraction of laterite nickel ore resources is proposed.
