The invention discloses a
rhodium reduction activation
dissolution method, and relates to the technical field of
noble metal metallurgy. The
rhodium reduction activation
dissolution method can be used for overcoming the defects of the prior art and aims at achieving a
rhodium dissolution method which has the advantages of high dissolution efficiency, wet method normal-pressure dissolution, easiness for operation, short process flow, low production cost and wide rhodium waste dissolution range. The technical scheme is as follows: the rhodium reduction activation dissolution method comprises the following steps of: A, crushing and
grinding rhodium wastes; B, mixing with an activating agent; C, carrying out acid-soluble activation; D, filtering; and E, dissolving. According to the invention, because
zinc powder and a
hydrochloric acid solution generate
chemical reaction in the step C to generate H2, rhodium
oxide contained in the solution can be reduced into
metal rhodium through H2 at 100 DEG C, the dissolution activity of rhodium can not be reduced and can be enhanced so as to be favorable to subsequent dissolution, and the rhodium
oxide is reduced into the
metal rhodium without being dissolved by
hydrochloric acid in the activated process. Thus, the rhodium reduction activation dissolution method disclosed by the invention has the advantages of high rhodium dissolution efficiency, rhodium normal-pressure dissolution, low dissolution temperature, easiness for operation, short process flow, low production cost and wide rhodium waste dissolution range.
