Due to the lack of missing economic technologies, within Europe more than 15 million tons of lead and zinc bearing slag from the ISF process were produced and landfilled within the last one hundred years. These heaps, presenting a potential source of environmental pollution, still contain metals that are not considered for European economy. The paper introduces an innovative solution for the reprocessing of ISF slags to recover valuables (zinc, lead, silver, iron and copper) and convert the clean residual phase into a raw material for construction purposes. Trials using a slag from North Macedonia have been conducted in technical scale, the upscaling is planned for 2020.Furthermore kinetic investigations on the reduction behaviour of zinc and iron in order to improve process efficiency are presented.
