Materials and Methods 2. 1. Materials The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe.
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. Nickel in laterite ores is often finely disseminated in various minerals in very fine size. Therefore, fine grinding can be useful to liberate ...

Dehydration and drying: After flotation, the water content of the material is relatively large, and the flotation concentrate material is sent to the thickener for ...
The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a concentrate which is then smelted to produce a nickel-enriched phase called matte, and further refined to ...
Flotation: Flotation is a widely used beneficiation technique for nickel ores. In this process, chemicals called collectors are added to the ore slurry to selectively attach to and float the valuable nickel minerals, while the gangue …
Based on the feasibility study, improved nickel recovery by DAF treatment of process water can bring economic benefits at a concentrator plant. 1. Introduction. The …
A plot of the graph of the parameter against its response on each level is referred to as the main effect and it indicates the general trend of influence of each parameter. Fig.2 shows the effect of the process parameters on flotation recovery of nickel. 113-6 Fig.2. Main effect of process parameter on nickel recovery.
Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity. The nickel ore had a content of 0.8 pct nickel …
Flotation process equipment is mainly composed of jaw crusher, ball mill, classifier, mixing tank, flotation machine, thickener and dryer and other main equipment. It is used for sorting non-ferrous metals such as copper, zinc, lead, nickel, gold, etc. It can also be used for rough selection and selection of ferrous metals and non-metals.
During the process of flotation, the galvanic effect occurs between a steel ball and the sulfide minerals during the grinding process. During the process of flotation, the different sulfide mineral particles also have galvanic interaction. ... The three nickel flotation plants (Mt Keith, Leinster mine and Kambalda Nickel Concentrator) in ...

Flotation constitutes a separation process that originated from mineral processing. Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or …
The anticipated demand for class 1 nickel products, particularly nickel sulfate, for the EV industry creates a unique opportunity to revisit the direct hydrometallurgical processing …
After flotation, the Cu and Ni enrichment ratios of the flotation concentrate increased by 0.3 and 0.2, respectively. Meanwhile, their corresponding recoveries increased by 4.2% and 3.1%. This study provides new insights for the treatment of copper–nickel sulfide ore to enhance the grinding and flotation process.
The challenges in processing nickel laterite ores using flotation process were comprehensively reviewed. Literature shows that flotation has not been successful to recover …
The grinding-flotation electrorefining process has such disadvantages as metal dispersion, complex process flow, and low recovery rate. This process has not been adopted in the newly emerging hydrometallurgical treatment facilities of high-grade nickel matte since the 1970s, but it still has industrial application in China, Russia, and Canada.
A sequential flotation process was proposed to separate arsenic-bearing minerals from copper concentrates (Fig. 15 ... Xu, M., 2016. Method for improving selectivity and recovery in the flotation of nickel sulphide ores that contain pyrrhotite by exploiting the synergy of multiple depressants. US Patent 9,387,490, 2016. Google Scholar. Doucet ...
To support the transformation to clean low carbon technologies, there is a demand for critical metals such as nickel. Awaruite is a less common nickel-bearing mineral with unique properties and responses to mineral separation. This paper presents the findings of a flotation study to recover awaruite from the Baptiste ultramafic deposit, located in central British …
Abstract Tecflote non-ionic organic agents are investigated as potential flotation collectors for copper–nickel sulfide ores. Adsorbability of four Tecflote agents having different-structure alkyl radicals and different numbers of functional groups is analyzed. The efficiency of the agents toward copper- and nickel-bearing minerals is estimated in non-frothing flotation of …
Gordon Process in 1955 was carried out by Totlani and Balachandra (1969) who studied ammonia pressure leach-ing of a copper-nickel concentrate containing 6.8% Ni and 4.5% Cu, copper being present as chalcopyrite (CuFeS 2), and nickel being present in a variety of sulfides.
To see the effect of closed water circulation on metallurgical performance, flotation tests were carried out with nickel concentrate thickener overflow water before and after the process of water ...
At the end of the flotation process, the nickel sulphides can be skimmed off and dried. Now at around 18% nickel, the concentrate is driven to Deception Bay, around 100km north of the mine. There it is loaded onto the Arvik I, a dedicated icebreaking bulk carrier ship, which transports it to the Port of Quebec.
Flotation practice differs by geographical location. Bulk sulfide flotation is generally carried out on Western Australian nickel ores which tend to be low in copper and contain substantial ...
Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery …
The aim of the hydrometallurgical process is the leaching of a nickel–pyrrhotite product followed by the flotation production of a nickel concentrate. The flotation hydrometallurgical processing of a nickel–pyrrhotite product makes it possible to produce nickel concentrates of a higher quality than those synthesized using a traditional ...
nickel in these ores while containing over 75 per cent of the sulphur. Therefore, efforts to reduce sulphur dioxide emissions from the smelting process have included the rejection of pyrrhotite in the milling stage as an alternative means of treatment. In the flotation process, a number of reagents are seen as a means ofdepressing pyrrhotite.
