POSSIBILITIES OF RECYCLING GALVANIC SLUDGE BY HYDROMETALLURGICAL METHODS

Popis výsledku v původním jazyce

This paper is a continuation of research in my dissertation, which deals with the possibility of recovering zinc from waste galvanic sludge, hydrometallurgical method of leaching. Galvanic sludges, which contain significant amounts of heavy metals, form waste suitable for hydrometallurgical recycling. Hydrometallurgical leaching method has already been tested as a suitable method of treating this type of industrial waste and recovering the two metals therefrom. Previous experiments have verified the leaching efficiency of these sludges in sulfuric acid at selected leaching temperatures and times. The aim of subsequent experiments is to obtain zinc by leaching several types of waste sludge samples in various acids and hydroxides, at several temperatures and time intervals. The electrolysis process under predetermined conditions followed, and the obtained product was further processed. The practical part also includes chemical and material analyses of leaching products.
