Possibilities of Processing of Galvanic Sludge Containing Useful Metals by Hydrometallurgical Processes

Popis výsledku v původním jazyce

The paper deals with the possibility of obtaining zinc and iron from waste galvanic sludge, which arise during galvanic plating. Galvanic sludge, which contain more significant amounts of heavy metals, form wastes that are suitable for hydrometallurgical recycling. The aim of the experimental and practical part was to obtain zinc and iron after leaching of galvanic sludge. Leaching was performed in sulfuric acids at different temperatures and time intervals with the addition of oxidizing agents as hydrogen peroxide or ozone. A separation of the leach and filtrate using filtration followed. The leachate was further processed by a precipitation of iron and other metals using various agents. After a further filtration the electrolysis was performed in order to obtain pure zinc on the cathode at the electrical voltage of approximately 3 V. All the partial products, i.e. the leachate, the leach liquor, the filtrate, the solid precipitate and the separated metal on the cathode were subjected to chemical analyses. The analyses results are presented in tables and graphs.
