Selective Reduction of Laterite Nickel Ore

nickel ore resources from sulphide ore becomes rare which makes nickel laterite ore as the future of nickel extraction. Unlike sulphide nickel ore processing, laterite nickel ore processing requires higherprocessing energy through smelting.Therefore, a novel method to process laterite nickel ore using lower energy is needed.

Nickel Laterite Ore Deposits: Weathered Serpentinites. Dominique Cluzel. INTRODUCTIONNickel laterites are intensely weathered regoliths with one or more horizons containing exploitable reserves of nickel (Ni), commonly, cobalt (Co) and, rarely, scandium (Sc). They are defi ned by economic, rather than geological, criteria, namely that the Ni-Co

Ochreous laterite: a nickel ore from Punta Gorda,

2001-7-1  Nickel laterite profiles generally comprise a saprolitic zone in which Ni is combined with silica (garnieritic ore) overlain by a leached zone in which Ni is associated with iron oxyhydroxides (oxidised ore). The oxidised ore is especially abundant in the Cuban lateritic nickel deposits (De Vletter, 1955, Lelong et al., 1976).

Roasting and Leaching Behavior of Nickel Laterite Ore

2021-3-29  Nickel can be found in laterite ores, sulfide ore, in secondary resources, and non-land resources like sea nodules.[6,7] However, only 40 pct of nickel scrap can be recovered as secondary sources, non-land resources require high investment and operational costs, thus, sulfides and lateritic ores are the most important nickel sources.[6,8,9,10

KINETIC MODELS OF NICKEL LATERITE ORE

The subject of this study is leaching process of nickel-bearing laterite ore from Ržanovo, R. Macedonia. The influence of sulfuric acid concentration (0.5, 1 and 3 M H2SO4) on the extracted Ni (%, wt.) was studied. The leaching process intensified by magnetic stirring at different temperatures (298, 323, 348 and 363 K) in the time interval of 120 min. was performed.

nickel Ore SlideShare

2016-1-28  FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore.

Kinetics of Atmospheric Leaching from a Brazilian

2020-10-7  The kinetics of atmospheric sulfuric acid leaching from a Brazilian nickel laterite ore was assessed using distinct reducing agents and ore mineralogy. This transitional ore contains 1.63% Ni distributed as 1.27% in coarse size (− 500 + 150 μm), mainly as silicates (lizardite and chlorite — 28.6%), and 2.06% in the fines fraction (− 75 μm), mainly as iron oxy-hydroxides (goethite and
