Zinc vapourisation from sludge wastes under thermal processing conditions: Zinc enrichment in HIsarna flue dust

HIsarna is a new furnace technology in the steel industry, featuring a large reduction of CO₂-emissions of up to 80%, and offering larger tolerances for gangue materials. Additionally, it has potential for zinc enrichment in the flue dust, as it can quickly vapourise zinc in the feed material and reject it to the flue dust. Increasing...
