Title: Method for rendering chromium-containing wastes of electroplating harmless
Inventor: KAYAK GERMAN L
IPC: C22B34/32
Filed: 1992-12-17
Granted: 1995-06-27
Abstract: FIELD: rendering chromium-containing wastes of electroplating harmless. SUBSTANCE: before fusion with iron, partial reduction of metal-containing oxides present in charge is effected by placing charge into reactor and reduction of metals-impurities, preferably, toxic, at temperature maintained at the level of temperature of evaporation of the most difficult to evaporate metal-impurity, and metals-impurities are taken from formed gaseous products by pumping gaseous products through cooling zone to cool them to temperature of condensation of the most easily evaporated metal-impurity. In so doing, carbon is used in the amount enough for complete reduction of all metal-containing oxides of precipitate. EFFECT: higher efficiency. 2 cl, 1 dwg
