Process for dissolving separating goods containing base metals and noble metals in metallic and / or alloyed form which develop hydrogen in contact with hydrohalic acid

摘要

A method for dissolving separating goods containing base metals and noble metals in metallic and / or alloy form in contact with hydrogen halide acid is presented, with: -Minimum concentration 1 mol / l and its temperature is +70 ° C to +90 ° C, the oxidizing agent containing halogen and forming a halogen atom compound with hydrohalic acid in acid, DOLLAR A b) addition of acid which forms halide ions in aqueous solution with dissolution of the Metal constituents, and DOLLAR A c) Adjust the resulting solution by adding a hydrohalic acid to a H · + · minimum concentration of 1 mol / l.
