Nickel in laterite ores is often finely disseminated in various minerals in very fine size. Therefore, fine grinding can be useful to liberate nickel-containing particles.
There are different methods for beneficiation of laterite nickel. Extraction of nickel from low-grade reserves usually is done by with metallurgical methods such as pyrometallurgy, hydrometallurgy, and physical methods. In approximately all of the pyrometallurgical processes three
May 01, 2012· 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
