| Zusammenfassung: | A wet process for extracting silver from high-Mn S-Fe-Ag ore includes such technological steps as grinding the ore, floatation to obtain ore concentrate, oxidizing calcination, desulfurization and dearsenization by sulfuric acid, impregnation extraction of ore concentrate, filtering, separation of solid from liquid, the secondary impregnation extraction of dregs, addition of 5-25% sodium chloridesolution to liquid to deposit silver chloride, and neutralizing the solution after deposition to recover manganese carbonate. Its advantages are high extraction rate and low pollution. |
