An increasing amount of precious metals, such as those in end-of-life electronics, end up in waste incineration furnaces. After incineration, specialized companies separate incinerator bottom ash into different fractions, with the fine non-ferrous concentrate containing most of the recoverable valuable and precious metals like silver, gold, palladium, lead, and copper. Focused on precious metal recovery, Umicore offers refining services to process the fine heavy-metal fraction (<20 mm), which has a high precious metal content. Despite its heterogeneous nature due to varying waste sources and preprocessing methods, our expertise ensures accurate sampling, assaying, and refining of the metals. With over 130 years of experience, we have the technology and know-how to efficiently recycle these complex materials.
