Rao et al. (1995) investigated the preconcentration of Ni values from the lateritic chromite ore overburden from Sukinda, Orissa, India. The Ni values were hosted in goethite, with no evidence of garnierite. The ore contained 0.54% Ni, 35.7% Fe, 40% SiO 2 and 6% Al 2 O 3 and needed to be upgraded to 1% Ni for the economic processing of this material using the …

Nickel is widely used in industrial processes and plays a crucial role in many applications. However, most of the nickel resource mainly exists as nickel oxide in laterite nickel ore with complex composition, resulting in difficulty in upgrading the nickel content using physical separation methods. In this study, high-grade ferronickel concentrates were obtained through …
