 · Several reports found that the largest saturation magnetization is observed at x = [14, 18,19,20], whereas, Kumbhar et al. showed that the maximum saturation magnetization is obtained at x = , Gabal et al. and Shinde et al. reported that the saturation magnetization increases with increasing concentration of nickel up to x = and then decreases with

Nickel Ore can be divided into copper sulfide nickel ore and nickel oxide ore, flotation is the main beneficiation method when processing copper sulfide nickel ore, magnetic separating and gravity separating are the commonly auxiliary methods. 【Application】

 · Mined sulfide ore, after crushing and grinding, is concentrated using flotation and magnetic separation. Subsequently, concentrates are smelted to produce nickel matte, which is further refined to produce pure nickel metal. Mineralogy plays an important role during flotation to separate nickel sulfides from gangue minerals. Apart from usual "trouble-makers", like talc

Because they contain much iron-nickel metal, all metal-bearing meteorites are attracted to a magnet. The concentration of nickel in iron meteorites and the metallic part of pallasites, typically 5-30%, is much greater than that in industrial metals except for high-nickel steels. The concentration of nickel in industrial iron is usually <1%.

 · Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods .

 · Ferronickel enrichment and extraction from nickel laterite ore were studied through reduction and magnetic separation. Reduction experiments were performed using hydrogen and carbon monoxide as reductants at different temperatures (700–1000°C). Magnetic separation of the reduced products was conducted using a SLon-100 cycle pulsating magnetic separator

 · After magnetic separation the main part is magnetic fraction and in slime tests this transition is more obvious. It can be assumed that the combination of gravitationally magnetic concentration methods and reductive sulfuric acid leaching of nickel ore makes it possible to produce standard platinum concentrate from sinter.

 · Spinel ferrite is the class of oxide materials with remarkable electrical and magnetic properties, which have been investigated and applied during the last few decades. Amongst all inverse spinel ferrites, the nickel substituted cobalt ferrite has been extensively studied in view of their good chemical and thermal stability, high electrical resistivity, magnetic anisotropy, high

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production. The specific processes

 · Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide nickel Laterites make up 70% of the world's nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world's nickel.

 · The reduced ore was then wet magnetic separated. The experiments show that high nickel content nickeliferous concentrate containing % Ni with nickel recovery of % could be produced with

 · Nickel is a hard silver white metal, which occurs as cubic crystals. It is malleable, ductile and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C. Five isotopes of nickel are known. In its metallic form nickel is chemically unreactive. It is

The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore from the gangue particles. Ore found in the earth

nickel ore deposits are closely associated with mafic and ultramafic in­ trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle. TYPES OF DEPOSITS All the

 · Separating nickel from sulfidic ores takes place using froth flotation tanks and magnetic processes. These produce two products – nickel matte and nickel oxide. These intermediate products contain between 40 and 70% nickel, but each requires further refining. Further processing of nickel matte occurs using the Sherritt-Gordon process. With this

Magnetic properties of maraging steels have been investigated as a function of nickel concentration. The alloys nickel content varied from 12 to 24 wt pct, while other alloying constituents were kept at a level maintained in the 18Ni-2400 MPA-grade maraging steel.

PRE-CONCENTRATION OF LOW GRADE LATERITIC SULPHIDE NICKEL ORE D F Denysschen and B N Wagner Multotec Abstract Dense medium separation is used extensively to pre concentrate low grade ores, making them cost effective to treat for the additional process stages which follow. In the past, the process has been limited to the recovery of diamonds,

The pre-concentration of nickel was attempted by magnetic separation, but was unsuccessful. The effect of the type of lixiviant, acid concentration, S/L ratio, time, and temperature were investigated in the atmospheric leaching process. Based on the experimental data, optimum conditions for the maximum recovery of nickel were determined under the following

At Nunavik Nickel, near the Expo open pit and for most of the Western portion of the property, the ore-bearing ultramafic intrusives are associated with very strong magnetic signatures, reaching 3,000 nT. It is interesting to point out that, as a result of mining, the two tailings north of the pit are now significantly magnetic. On the other end, over the eastern portion of the property, the

Dumont Nickel Project is a nickel sulphide (NiS) deposit lying in the Abitibi-Témiscamingue region of Quebec, Canada. The mine falls within the precincts of Launay and Trécesson municipalities and is located approximately miles (25km) north-west of the city of Amos, 37 miles (59km) north-east of the city of Rouyn-Noranda, and about miles (70km)

Increase of the temperature and concentration of the solvent leaching process of the nickel laterite ore is diffusionally controlled. (H2SO4) significantly intensifies the leaching process intenisfied with magnetic stirring. 2. The leaching process in 3M H2SO4 in the whole studied Activation energy analysis temperature range is the best described by Jander and Ginstling-

 · The concentration ratio of the amount of gold and platinum in the magnetics to that in the nickel fraction was 10:1. The tendency of gold and platinum-group metals to concentrate in the magnetic iron-nickel alloy could be used to recover an enriched precious-metal concentrate by recycling the magnetics to the next batch of molten matte and allowing

Because chondrites are rich in metal and the metal is rich in nickel, all chondrites have a bulk (whole rock) concentrations of Ni (nickel) of % (, 10000-18000 ppm). That's 100-1000 times greater than practically any terrestrial (Earth) rock. An Earth rock with as much as % Ni would be a nickel ore.

 · Nickel Ores and Minerals. To test the presence of nickel in a mineral, by means of the blowpipe, requires great care. If heated on charcoal, together with carbonate of soda in the inner flame, a grey metallic powder, attractable by the magnet, is formed. If heated with borax on platinum wire in the outer frame, a hyacinth red to violet brown

Concentration of nickel values in oxidized oresof the nickel in the ore is reduced from the gaseous state to the metallic state and can be easily separated from the ore by magnetic separation techniques or, after suitably activating the precipitated metal values, by flotation techniques. Although the length of time the mixture is held at these temperatures will vary from
