Aluminum saline slags is a waste of the metallurgical industry that presents serious environmental problems since it needs very extensive areas for its disposal, toxicity causes in atmosphere and groundwater, addition to high transportation costs. The valorization this residue by synthesis alumina, compound widely used chemical industry, generates impact great interest. In work, strategies synt...

Increasing crop productivity and minimizing greenhouse gas emissions from paddy fields are increasingly receiving attention. Slag application not only can maximize the use of solid wastes as beneficial resources for agricultural production, but it also reduces emissions. In order to determine most effective slags soil amendments emission reduction, three major slags, i.e., steel, titanium manga...

This study provides insights on the formation of crystalline phases from Fe-rich slag-based porous inorganic polymers (porous IPs), cured under hydrothermal conditions. The IPs were synthesised using synthetic slags with different chemistries (from FeO-SiO 2 -CaO to -Al O 3 systems) as solid precursors, and a sodium silicate-based alkaline activator. Chemical expansion was used create structure...

Abstract The world of stainless steel production was 52 Mt in 2019, and the annual amount slags including electric furnace, AOD converter, ladle, casting tundish, estimated at 15–17 Mt. Nowadays, only a minor fraction from is utilized major part goes to landfilling. These contain high-value elements (Cr, Ni, Mo, Ti, V…) as oxides or metallic form, some them being environmentally problematic if ...
