<p>Apparatus for producing drest iron-ore briquette from steel making converter flue-dust, converter sludge or red mud, comprising converter flue-dust storing container (1), reagent container (2), autoclave (4), buffer vessel arrangement (6), separator (7), dryer unit (8), buffer vessel (5), evaporator (12), water cooler (13), driving water vessel (3) and separator unit (14), characterized in that the apparatus is further provided by a mixing unit (9) with pouring slot (10) and a briquetting unit consisting of an endless casting mould belt (11) stretched between two belt drums (D1, D2), and driving means connected to at least one of the drums (D1, D2), and open casting moulds (Ha) with closed bottom and cavity walls (Hf) made of elastic material are arranged in at least one row on the endless belt (11). In one of the methods according to the invention the heavy metal (Me) content of converter flue-dust and/or converter sludge is transformed into Me-chloride and Me-ferrite or Me-salt, and its Fe-oxide content is transformed into colloid solid phase, and the latter yet containing Fe-oxide is forwarded from the separator (7) into the mixer (9) then added CaO containing material, and mixing this mixture up to get a pasty state iron-ore pulp, then this pulp is poured into the casting moulds (Ha) of the endless casting mould belt (11) stretched between two belt drums (D1, D2).</p> |
