Regeneration method for rhenium-containing high-temperature alloy scrap

The invention discloses a regeneration method for rhenium-containing high-temperature alloy scrap, comprising the following steps of: 1, performing atomizing treatment; 2, performing acid dissolution; 3, performing solid-liquid separation to obtain a filtrate a and filter residue b; and 4, treating the filtrate a and the filter residue b respectively, wherein the treatment process for the filtrate a is as follows: separating element Re, precipitating the solution after separating the element Re and removing impurities from the solution, and separating element Ni from element Co in the solution after removing impurities; and the treatment process for the filter residue b is as follows: performing oxidation treatment, filtering, separating out element W and element Mo in the filtrate after filtering, and separating out element Ta and element Hf in the filter residue via acid dissolution after filtering. The method disclosed by the invention is simple in steps, convenient to realize, low in ...
