We can customize nickel ore beneficiation process and equipment to achieve comprehensive utilization of …
Over 30 magmatic Ni-Cu-Co sulfide deposits have been discovered in China (Fig. 1), two of which are the world-class Jinchuan deposit and the super-large Xiarihamu deposit, with nickel metal resources exceeding one million tonnes representing ∼80% of China's nickel and cobalt resources [21].China's earliest discovered magmatic …
Table 2 Distribution of Ni and S in sulfide ores Ore source Nickel distribution (%) Sulfur distribution (%) Pentlandite Pyrrhotite Pentlandite Chalcopyrite Pyrrhotite ... was found to be due to the process water containing heavy metal ions such as Ni2#,Cu2#,Ag2#, which were causing the inadvertent activation. By using
Nickel sulfide concentrates are critical materials for the production of metallic nickel. The disadvantages associated with the conventional nickel extraction process are the considerable amounts ...
The possibility of applying a combined concentration and metallurgical method for processing low-grade and refractory copper–nickel ores was considered. The resulting rougher and scavenger flotation concentrate contained 2.07% nickel and 0.881% copper at a recovery of 85.44% and 89.91%, respectively. The concentrate was then …
The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover nickel from laterite ores. ... However, this work is not included in Table 1 as the ore they used was indeed a nickel sulphide, but the authors had classified it as lateritic ...
In anticipation of future demands, a comprehensive understanding of the chemical and mineralogical characteristics of nickel-bearing minerals is a prerequisite to devising effective nickel beneficiation methods. Of particular importance are markers in the mineralogy of the flotation concentrate that inform beneficiation strategies to improve …
Nickel deposits in the world can be divided into three categories: copper-nickel sulfide ore, laterite nickel ore and weathered crust nickel silicate ore. At present, nickel sulfide ore is the main source of nickel metal. Although the extraction of nickel from nickel oxide ore is becoming more and more popular, nickel sulfide ore is still the …
Nickel is an important strategic metal resource, which plays an important role in national defense, aerospace, new energy and other fields. In recent years, low-grade nickel sulfide ore (LGNSO) has become the main raw materials for nickel extraction due to the depletion of high-grade nickel sulfide ore resources [1].However, the effect of the …
This paper reviews historical and current data on global nickel production, resources and ore types, focusing on sulfide and laterite ores. It also discusses the …
Nickel processing, preparation of the metal for use in various products. ... As early as 200 bce the Chinese made substantial amounts of a white alloy from zinc and a copper-nickel ore found in Yunnan province. The alloy, ... Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have ...
The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...
The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It was found that an iron-oxidizing strain of acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching of sulfide ores from the deposits in Russia's Murmansk region. Sulfide mineralization of the studied …
Direct hydrometallurgical processing of whole nickel sulfide ores has also received considerable attention, particularly bioleaching, which was the subject of a review by Watling (Citation …
The former constituents approximately 40 pct of the total ore reserves and account for half of the nickel production worldwide [1, 2]. Smelting followed by refining is the conventional technology to extract nickel from the sulfide ores as metallic nickel. However, during the smelting process, significant amounts of sulfur dioxide are …
