Due to its properties, tantalum is a metal with versatile applications. Especially in its main application as a component of tantalum capacitors in electronics, the recycling rate for end-of-life products is still below one percent. The IRETA project is therefore developing new ways of recovering tantalum from printed circuit boards. Automated optical recognition identifies the components and then removes them from the printed circuit board using laser technology. The epoxy resin is separated from the tantalum anodes by mechanical processing, density separation and magnetic separation. A large part of the silver contained in the capacitors is thereby also extracted from the tantalum and can be recovered. In addition, an electrochemical purification is carried out for further concentration of tantalum. Based on a statistical evaluation of the input material and the expected process costs and revenues, a material flow cost analysis of the developed recycling route is prepared.
