.%. The results of the investigated process indicated the possibility of extracting nickel directly from nickel-based superalloy scraps. Key words: superalloy; zinc; nickel; extraction; vacuum separation 1 Introduction Superalloys are advanced high-temperature materials with iron, nickel, or cobalt as the matrix metal with excellent high-temperature strength, fatigue resistance, fracture toughness......
Construction of nickel cobalt sulfide nanosheet arrays on carbon cloth for performance-enhanced supercapacitorTao Liu1,Jiahao Liu1,Liuyang Zhang1,Bei Cheng1,Jiaguo Yu1,21. State Key Laboratory..., a novel strategy for the growth of nickel-cobalt bisulfide(Ni Co S) nanosheets arrays on carbon cloth(CC) as supercapacitor electrodes is reported, involving deposition of two-dimensional metal-organic......
processes, were usually focused on the utilization of nickel in laterite ore, and more attention was paid to the recovery of nickel than that of cobalt. In fact, cobalt recovery provided an important revenue... from limonite-type laterite ores due to its low reactivity with goethite, in which nickel was involved[6-7]. In this work, extraction of cobalt from limonite-type laterite ores was studied by citric......

Materials..." name="ChDivSummary">The present investigation involves the separation of zinc and nickel from a sulfate solution using the acidic leaching of zinc plant residue after cadmium removal step......
℃, and the manganese sulphate is obtained by concentrating the resulting solution. By re-dissolving the precipitates of cobalt and nickel, the separation of cobalt and nickel is performed using di(2-ethylhexyl... mono-2-ethylhexyl ester (EHEHPA, commercially known as PC88A or P507), have been widely used for separation of Co from Ni[11]. Recently, the simultaneous extraction and separation of cobalt and nickel from......
