China is the world's largest steel producer, with Iron and Steel Association estimating that country's crude production in 2022 will be 935 million tonnes [Citation1]. In 2017, metallurgical slag output of iron enterprises reached more than 440 tons, including 247 tons blast furnace 101 converter [Citation2]. After accumulation recent years, current number waste huge. By 2020, total amount indu...

Magnetosensitive biochars were prepared with mechanochemical ball-milling of lignin and blast furnace dust further pyrolysis at 800 °C under an inert gas atmosphere. The physicochemical sorption characteristics the materials analyzed using several techniques: low-temperature nitrogen adsorption–desorption, X-ray powder diffraction, Raman spectroscopy, elemental analysis, potentiometric titratio...

The prospects of processing blast furnace and steelmaking sludge using the Waelz process in a laboratory rotary kiln, is shown. influence different temperatures, atmosphere type reducing agents on level zinc reduction from sludges was analyzed. In general, contains high portion iron (approx. 48 wt.%) can be reused as charge after satisfactory reduction. It found that N- content graphite or coke...
