Flotation of nickel sulfide ore is a key process in the separation and subsequent utilization of nickel However efficient separation of nickel is hindered by the presence of magnesium silicates typically serpentine [2] that caused hetero aggregation and foam entrainment The exposed surface of pentlandite is positively charged and adheres
In this paper the flotation behaviour of nickel copper ores processed in the Sudbury area is discusse with emphasis on the effect of oxidation on individual minerals pnmarily pyrrhOlite In general moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate
Serpentine Mg Fe 3 Si 2 O 5 OH 4 is a typical magnesium bearing silicate gangue mineral in nickel sulfide ore which seriously interferes the flotation enrichment of pentlandite Fe Ni 9 S 8 Kusuma et al 2014 Until now the microscopic interference mechanism of serpentine towards pentlandite enrichment is basically clear which includes

Keywords Flotation nickel sulphide serpentine lizardite chrysotile carboxy methyl cellulose slime dispersion salt water INTRODUCTION Western Mining Corporation mines several nickel sulphide deposits in the Eastern Goldfields region of Western Australia north and south of Kalgoorlie Concentrates are railed to the flash smelter at
Abstract The possibilities of extracting valuable components and producing selective good quality concentrates from hard to beneficiate crude ores are considered for the disseminated copper nickel ores from the Norilsk district The stated aim is achieved by a combined technology including beneficiation and hydrometallurgical processes Beneficiation is
Nickel smelting slag contains valuable metals including nickel and copper Failure to recycle these metals wastes resources and disposal of nickel slag in stockpiles results in environmental pollution Nickel slag recycling is important and metals can be recovered from slag by flotation However considering the complex forms in which valuable metals occur in
addition on flotation performance of a nickel sulphide ore The objectives of the study were to 1 develop an understanding of the effects of collector and depressant dosage and its interactive effects on flotation performance and 2 determine the effect of stage dosing collector and depressant on flotation
The FTIR DRIFT and FT Raman studies of the products of copper nickel ore flotation have recorded the presence of goethite iron sulphates and sulphur element on the surface of mineral grains It is a characteristic that the elemental suphur peaks intensity decreased in the spectra on transition from the concentrate of between bath to basic
Abstract The coprecipitate flotation of 137 Cs from dilute aqueous solutions and simulated radioactive wastes using nickel hexacyanoferrate II as a coprecipitant and sodium lauryl sulfate cetyltrimethylammonium bromide or dodecyl amine as a collector was extensively investigated to establish the best conditions for cesium removal Under the optimal conditions
In sulfide ores nickel is primarily hosted in pentlandite and occasionally in pyrrhotite with associations of Co Cr Mn Cu and Mg Meshram and Pandey 2018 As such during extraction froth flotation is conventionally used to produce Ni rich concentrates followed by pyrometallurgical smelting Meshram and Pandey 2018 Park et al 2006
The iron to magnesium ratio in the nickel concentrates destined for smelting is a key parameter that influences smelting temperature and slag viscosity Mayhew et al Citation 2013; Senior and Thomas Citation 2005 hence emphasis is placed on the rejection of Mg bearing gangue during flotation of nickel sulfide ores Lotter et al Citation
1 Introduction Pentlandite flotation in Western Australia has historically been difficult due to a low nickel grade and large amounts of serpentine minerals Senior and Thomas 2005 The hypersaline water used in the flotation plants makes the traditional serpentine dispersants ineffective Wellham et al 1992 In the past 10 years many studies have been
Immediately after copper flotation the circuit was conditioned for nickel flotation 50 g/t of sodium isopropyl xanthate SIPX Nasaco was the nickel collector 15 g/t of CMC depressant and 10 g/t of Nasfroth 240 frother were used for 15 min C3 and C4 Immediately after 30 g/t of SIPX was added to collect C5 and C6 the slow floating
explored in the context of combining nickel laterite and nickel sulfide leaching into a single unit operation where the acid and heat required for nickel laterite leaching is generated in situ by oxidation of the iron sulfide component Ferron and Fleming 2004; McDonald and Li 2020; McDonald et al 2012; Quinn
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
