Incineration bottom ashes
Increasing precious metals containing materials, such as end-of-life electronics, end up in incineration furnaces. The remainder bottom ashes contain both metallic and mineral fractions that can be further processed to extract precious metals. Umicore has the technology and the expertise to accurately sample, assay and refine these complex, precious metals bearing materials. Most precious metals are found in the fine heavy non-ferrous fraction from bottom ashes.
