description The invention belongs to the technical field of extraction, and particularly relates to a method for extracting and separating nickel, cobalt, tungsten, molybdenum and vanadium, which comprises the following steps: extracting and separating a to-be-treated water phase containing nickel, cobalt, tungsten, molybdenum and vanadium ions from an extracted organic phase to obtain a loaded organic phase enriched with the tungsten, molybdenum and vanadium ions and a raffinate water phase enriched with the nickel and cobalt ions; the extraction organic phase is an acidified organic phase containing an extraction agent # imgabs 0 #, an extraction agent # imgabs 1 #, an extraction agent # imgabs 2 # and a diluent, wherein the extraction agent # imgabs 1 #, the extraction agent # imgabs 2 # and the diluent are shown in the formula 1. On the basis of the technology, co-extraction of tungsten, molybdenum and vanadium ions can be achieved, and in addition, high-selectivity extraction and separation of tungsten, molybdenum a
