Beneficiation of nickeliferous laterite by reduction ...

2012-5-1  Nickel in nickeliferous laterite is closely associated with iron oxide and silicate minerals as isomorphous substitution for iron and magnesium in the lattice. Laterites are not amenable to beneficiation by physical methods due to their complex mineralogy (Dalvi et al., 2004, Warner et al., 2006). Thus, for laterite ores treatment, pyrometallurgical or hydrometallurgical methods are usually

Metallurgical Beneficiation of Iron Laterite Ores with

2019-6-13  (1) We developed a new process of metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel–cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions, the fragmentation of the roasting product, and subsequent magnetic separation of metallic and slag phases.
