Accelerated carbonation and leaching behavior of the slag from iron and steel making industryD. C. Johnson,C. D. Hills摘 要:Ground granulated blast furnace slag(GGBFS)and steelmaking slag have been used as a raw material for cement production or as an aggregate to make concrete,which contribute aluminum,calcium,iron,and silicon oxides.The suitability......
is a promising method for reducing carbon dioxide in a largescale setting. Existing calcium oxide or calcium hydroxide in steelmaking slag can be easily leached by water, and the formed calcium carbonate can... was evaluated. Results showed that dilute alkali solution participated in slowing down the leaching of active calcium in the steelmaking slag and in significantly improving carbonation conversion......

contents of CaO and Fe2O3 in slag, but change little with change of temperature. The results can be applied to the thermodynamic research of new copper smelting technologies adopting calcium ferrite slag. Key words: calcium ferrite slag; coexistence theory; activity; calculation model 闪速吹炼,三菱连续吹炼,Glogow直接闪速炼铜等现代火法炼铜工艺因具有节能,环保,高效等优点,近年来在世界各地得到推广应用[1].随着氧势的提高,吹炼或造粗铜炉渣中Fe3O4和Cu2O的含量不断增加,为了避免形成固体磁铁......
