Document Type and Number:
WIPO Patent Application WO/2024/056116
Kind Code:
A1
Abstract:
The invention relates to a magnetic adsorbent based on slag from an iron or steel metallurgical production process, in particular based on ladle furnace slag, for adsorbing ions from an aqueous environment, wherein said magnetic adsorbent comprises Ca in an amount expressed in the form of CaO containing at least 50 wt. % CaO, Al in an amount expressed in the form of Al2O3 containing at least 7.5 wt. % Al2O3, Si in an amount expressed in the form of SiO2 containing at least 5 wt. % SiO2, Mg in an amount expressed in the form of MgO containing at least 2 wt. % MgO, and at least one magnetically active iron oxide selected from the group consisting of Fe2O3 and Fe3O4 and in an amount expressed in the form of Fe containing at least 2.5 wt. % Fe. The invention further relates to a method of producing said magnetic adsorbent and to use thereof for adsorbing Be2+, Sr2+ and/or Ce4+ ions from an aqueous environment.
