Abstract
The possibility of tantalum recycling from waste of electrical and electronic equipment was investigated. Study was carried out using basic physical and chemical methods, ie. mechanical separation via crushing, leaching of silver layer in diluted HNO3, grinding and oxidation of anodes and thermic reduction with metallic reducing agent. A recovery rate of anodes was determined at 96%, and recycling efficiency of tantalum to pure form was determined more than 50%. Also was made mass balance.
