Outline of Final Research Achievements	In this study, it is investigated that the possibility of nickel brazing production with the aim of nickel recovery as a value-added material from electroless nickel plating waste liquid. This research revealed following three points, the method of concentrating nickel included in waste liquid on lignite, the optimum conditions for the production of nickel fine particles upon steam gasification of nickel-loaded lignite, and, the recovered nickel fine particles melt less than 1273K. These results suggest the possibility of nickel brazing production from waste liquid of electroless nickel plating process.
