This chapter describes nickel sulfide ores and provides an overview of the methods used to extract nickel and cobalt from these ores. Nickel sulfide ores occur as disseminated or massive ore bodies. Most of the cobalt and nickel in the Lead Belt ore is present as the min eral siegenite, (Ni,Co)3S4 ' Siegenite is a member of the linnaeite series of minerals and sometimes contains some copper and iron. In Missouri ores, the cobalt-nickel-bearing minerals are best characterized by a complex interlockFile Size: 1MB.

Figure 3 shows that 93% of chalcopyrite can be recovered in 12 min in the presence of SO 2, but the co-recovery of 12% pentlandite and 23% III/NICKEL AND COBALT ORES: FLOTATION.
The bioleaching behavior of copper and nickel from a low-grade nickel, copper, and cobalt-bearing sulfide ore was investigated. A recovery of 94% Ni, 62% Co and 70% Cu was achieved in 68 days of. Cobalt (Co) is a potentially critical mineral. The vast majority of cobalt is a byproduct of copper and (or) nickel production. Cobalt is increasingly used in magnets and rechargeable batteries. More than 50 percent of primary cobalt production is from the Central African Copperbelt. Single phase cobalt disulfide (CoS 2) nanoparticles were prepared by thermal decomposition of cobalt‐thiourea complex at a low temperature ( °C).CoS 2 nanoparticles exhibit ferromagnetic ordering at K below which the temperature dependent resistivity of cold pressed nanoparticles deviates from metallic behavior and shows a broad maximum. Just below T C, it also exhibits a large. Sulfide Ore Plant Nickel. 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 Learn More.
A sequential flotation process for the recovery of high-grade concentrates of copper, lead and cobalt-nickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper. The bioleaching behavior of copper and nickel from a low-grade nickel, copper, and cobalt-bearing sulfide ore was investigated. A recovery of 94% Ni, 62% Co and 70% Cu was achieved in 68 days of flask leaching including 18 days of acid pre-leaching and 50 days of bioleaching. Recovery from copper-cobalt sulfide concentrates. The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble calcine is subsequently leached with sulfuric acid from the spent copper recovery concentrates are introduced at this leaching step to maintain the acid balance. Trace element studies of sulphides have been used to estimate temperatures of mineral formation, to identify metallogenic provinces, and to investigate the environment of mineral deposition. In the investigation of depositional environments, the Co:Ni and S:Se ratios are potentially useful as discriminators between magmatic-hydrothermal and sedimentary environments.
