ABSTRACT The selective reduction of nickel and adequate growth of ferronickel grains are imperative for efficient preparation of ferronickel from nickeliferous laterite ore via the process of direct reduction followed by magnetic separation. In Part I, reduction/sulfidation behaviors of a saprolitic laterite ore in the presence of sodium …

Recovery of Nickel and Processing of Magmatic Sulfide Ores. The processing of magmatic sulfide ores differs from laterites: sulfide ores are crushed in multiple steps to separate the ore minerals from the gangue. At each stage the ore is separated by size, using vibrating screens, as well as magnetic separation of iron-rich …

In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash …
