<p>The invention relates to a method for processing steel slags and optionally ferriferous materials such as e.g. electric furnace slags, converter slags, dust produced during the manufacturing of steel, rolling mill cinders or secondary metallurgical tailings. According to the inventive method, the molten steel slags or ferriferous materials are mixed with chrome ores or wi th dust containing chrome and/or nickel in order to adjust the slag basicity to a level ranging from 1.2 to 1.6, whereby the bath temperature is maintained at a temperature greater than 1600 ~C, especially between 1650 ~C and 1800 ~C, an d an Fe bath containing carbon is provided or configured. In addition to the environmentally compatible slags, a high-quality ferrochrome alloy can be obtained, whereby the economic efficiency of the method is improved.</p> |
