A method for producing liquid ferroalloy by direct processing of manganese and chromium bearing iron compounds, by the steps: of mixing carbonaceous reductant, fluxing agent, and a binder with materials such as iron sands, metallic oxides, manganese-iron ore concentrates and/or chromium-iron ore concentrates and silica sands, to form a mixture; forming agglomerates from the mixture; feeding the agglomerates to a melting furnace with other materials; melting the feed materials at a temperature of from 1500 to 1760°C and forming a slag and hot metal; removing the slag; and tapping the hot metal as liquid ferroalloy.

L'invention concerne un procédé de production de ferro-alliage liquide par traitement direct de composés de fer porteurs de manganèse et de chrome. Le procédé comprend les étapes consistant: à mélanger un réducteur carboné, un fondant, et un liant avec des matériaux tels que des sables ferrifères, des oxydes métalliques, des concentrés de manganèse-fer et/ou des concentrés de chrome-fer et des sables siliceux, afin de former un mélange; à former des agglomérats à partir du mélange; à acheminer les agglomérats dans un four de fusion avec d'autres matériaux; à faire fondre les matériaux de charge à une température comprise entre 1500 et 1760°C et à former des scories et un métal chaud; à évacuer les scories; et à soutirer le métal chaud sous forme de ferro-alliage liquide.
