Hydrometallurgical methods of galvanic sludge processing

Abstract

The paper deals with the possibility of obtaining zinc and iron from waste galvanic sludge, which arises during galvanic plating. The practical part describes laboratory experiments of the hydrometallurgical process of leaching in acids, with the addition of oxidizing agents. Subsequent chemical analyzes of leachate and leachate. Finally, other procedures for possible recovery of metals as secondary raw materials are indicated.
