·Basic oxygen furnace slag BOFS is a high volume waste resulting from the production of steel from pig iron Due to its high free lime content BOFS is difficult to recycle and/or include into conventional cement systems Alkali activation technology offers a pathway to transform industrial wastes such as BOFS into low carbon cements Alternative precursors for
·Induction furnace slag contains almost the same amount of Fe 2 O 3 as an electric arc furnace at 29% but a higher amount of Al 2 O 3 [92]
·In order to explore the difference of the activation effect on the ground granulated blast furnace slag GGBFS subjected to variant activators as well as to further clarify the depolymerization mechanism of GGBFS investigation on the dissolved mechanism hydrated characteristics and microstructural evolution were carried out based on slag immersed in
·Blast furnace slag BFS which is defined as the non metallic product consisting essentially of silicates and alumina silicates of calcium and other bases that is developed in a molten condition simultaneously with iron in a blast furnace by ASTM C 125 16 2016 has been widely used in construction industry for more than 80 years When the mixture of iron ore
·In the present study Blast Furnace Slag BFS waste was evaluated as a sustainable cost effective CaO SiO2 Al2O3 and MgO substitute for inorganic oxides for the production of frit a raw
·The alkali activated blast furnace slag is attracting significant attention in replacing Portland cement due to several characteristics similar to cement hydration However there are a few practical problems with commercial alkali activators such as the fast setting time relatively high costs and significant CO2 emissions during preparation Thus discovering
·The slag generated from a steelmaking cycle is later processed and the final product after processing is referred to as basic oxygen furnace slag BOF slag The chemical reactions occurring during the removal of impurities determine the chemical composition of the basic oxygen furnace slag [1 3 5]
·Basic oxygen steelmaking BOS slag a product of hot metal element Si Mn Fe P oxidation and flux lime dolomite dissolution plays a critical role in the production of high quality crude steel although its behavior inside the BOS vessel formation and reaction with metal droplets and gas is still not clear and its recycling has always been challenging
·In the process of gas granulation of blast furnace slag a cyclone separator serves to cool slag particles and separate them from hot air This study focuses on modelling the cooling of slag particles in a cyclone separator Simulations revealed the airflow field temperature field and particle trajectory distribution within the cyclone separator Key parameters such as
·During the last few decades the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized The electric furnace or rotary slag cleaning furnace are now generally used to perform this task giving a level of copper in discard slag typically in the range of wt % and wt % with most plants reporting copper losses in
