Method for recovering valuable constituents in cyanide-containing waste water of gold mines
A method for recovering valuable constituents in cyanide-containing waste water of gold mines includes removing interfering ions Fe(CN)42- and SCN- in the cyanide-containing waste water under synergistic effect of Cu2+ and Na2SO3; adsorbing Cu(CN)43- and Zn(CN)42- in solution by strongly-alkali ion...

| Zusammenfassung: | A method for recovering valuable constituents in cyanide-containing waste water of gold mines includes removing interfering ions Fe(CN)42- and SCN- in the cyanide-containing waste water under synergistic effect of Cu2+ and Na2SO3; adsorbing Cu(CN)43- and Zn(CN)42- in solution by strongly-alkali ion exchange fibers after the interfering ions in the solution are removed; desorbing the adsorbed fibers by hydrochloric acid after the Cu(CN)43- and Zn(CN)42- are separated from the cyanide-containing waste water, and finally comprehensively recovering valuable constituents in the cyanide-containing waste water. |
