| 摘要 |
The invention provides a method of processing a starting material in the form of a metal oxide-containing raw metallurgical slag to obtain a processed slag product . The method includes admixing the raw slag with a reductant to obtain a reaction mixture and heating the reaction mixture to cause the reductant to reduce the metal oxide in the slag, to obtain molten metal, in particular containing f erromanganese, and molten processed slag, in particular having a manganese content of at most 10% by mass. The method further includes separating the molten processed slag from the molten metal and causing or allowing the molten processed slag to solidify, thereby to obtain a solid processed slag product. This processed slag product may be, as desired, a filler for use in brick-making or for use in formulating a ready-mix concrete, an extender for extending a cement or for producing a blended cement, or an aggregate for use in the construction or building industry. |
