In Kenya, Iron ore deposits have been documented to exist in laterites, in various parts of Kenya 3-5. Previous studies have shown that iron in laterites is fairly widely spread all over the country and contain 15 to 45% iron depending on source. Iron in these laterites are mainly in the form of ilmenite, haematite and goethite 6.

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
