The direct reduction roasting-magnetic separation experiment was conducted on nickel laterite sample A, which graded 0.97% Ni and 40.09% Fe, and B which graded 1.42% Ni and 23.16% Fe, to research existing state and regularities of distribution of nickel laterite ore, and to explore intensify method of direct reduction by ore blending. The results show that Ni reserves mainly in goethite lattice in limonite nickel laterite ore, and the grade of Ni is also high in lizardite. In humous nickel laterite ore, iron-magnesium silicate is main mineral, which has low grade of Ni, and goethite is secondary mineral, which has high grade of Ni. It can reduce reduction temperature and Fe/Ni by ore blending, and control reduction of iron cooperating additional agent. And concentrate assaying 6% nickel was thus manufactured at a recovery of 92.08%. Ni mainly enriched in yFe-Ni and little distributed in other phase in reduced roasting ore, which realizes selective reduction and beneficiation.
