During a one-week campaign, the flexibility and technical superiority of the HENRI Smelter was impressively demonstrated. In nine batches over five days, a total of 23 tonnes of various e-scrap concentrates were processed – from highly metal-bearing concentrates to printed circuit boards and shredder light fractions.
As a result, the process stability and efficiency even beyond common raw material mixes was successfully shown. Besides conventional slags, also new slag Systems that allow higher concentrations of light metals in the feed material were used. Moreover, extensive off-gas measurements helped to further optimize the environmental technology of UrbanGold plants. Our aim is to not only meet legal framework conditions, but to pave the way for a new standard in e-scrap recycling.
