nickel processing Extraction and refining | Britannica

nickel processing nickel processing Extraction and refining: 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 inAfter producing the nickel matte, further processing is done via the SherrittGordon process First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%Nickel: smelting, producingMetalpediaDec 07, 2021· 高达10%返现· Selective precipitation made it possible to obtain nickel concentrates with the content of nickel ranging from 153 to 982% for the first two methods, whereas in the case of the third method based on a dimethylglyoxime solution, the obtained nickel concentrate purity was 943% The process of leaching nickeldimethylglyoximeObtaining Nickel Concentrates from Sludge Produced in the
