The paper deals with the possibility of obtaining zinc from waste galvanic sludge, which arises during galvanic plating. Galvanic sludges, which contain significant amounts of heavy metals, form waste suitable for hydrometallurgical recycling. This method has already been proven as a suitable way of treating this type of industrial waste. The aim of the experiments is to obtain zinc by leaching several types of waste samples in different acids and hydroxide, at selected temperatures and time intervals. The leaching process will be followed by electrolysis of the leachate and recovery of the product as a secondary raw material. The practical part also includes chemical and material analyses of leaching products.
