Extraction of nickel and cobalt from reduced limonitic

Reduced ore samples were obtained from the reduction roasting of a limonitic laterite. The extraction of nickel and cobalt from the reduced ore was conducted by selective chlorination in the temperature range of 300–500 °C using aluminum chloride hexahydrate as the chlorination agent, and followed by water leaching at 80 °C.

Lateritic nickel ore deposits Wikipedia

Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.

Extraction of Nickel, Cobalt and Iron from Laterite Ores

Primary nickel is produced from both lateritic and sulfidic ores. Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by

Extraction of Nickel and Cobalt from Acidic Solutions

LIX63 in combination with DNNS selectively extracts nickel and/or cobalt from acidic leach liquors with pH values as low as 1.0. Nickel/cobalt and cobalt/nickel selectivities are achieved by varying the relative concentrations of LIX63 and DNNS. Increasing LIX63 concentration retards both extraction and stripping rates while DNNS has the opposite effect.
