Method for dissolving noble metals out of segregated ores containing noble metals.

摘要

Process for dissolving precious metals for separated material containing precious metals comprises reducing precious metal oxides to the individual metals in finely divided form, and reacting the separated material and/or the precious metals with HCl and chlorate. The solution/suspension produced has a concentration of H<+> ions of at least 1 mol/l, a concentration of Cl<-> ions of at least 1 mol/l and a temperature of at least 50o C.
