Description
Обогащение железных мышь ковистых руд, с целью снижени в них мышь ка, производитс различными способами с использованием магнитной сепарации, обжига, агломерации .Iron micelles are enriched with iron ores, in order to reduce them, by various methods using magnetic separation, roasting, and agglomeration.
Предложено железную мышь ковистую руду размалывать до величины зерна 1 мм или флотационной тонкости, смешивать с . измельченными до такой же степени восстановителем и известн ком, вз тыми в таком соотношении, что образующа с двуокись углерода минимум в два раза превышает окись углерода; затем смесь окомковывают или брикетируют и быстро нагревают до температуры спекани или сплавлени .It was proposed to grind iron iron mouse to grain size of 1 mm or flotation fineness, mix with. crushed to the same extent with a reducing agent and lime, taken in such a ratio that the carbon dioxide produced from carbon dioxide is at least twice as high as carbon monoxide; the mixture is then pelleted or briquetted and quickly heated to the sintering or fusing temperature.
В случае обнаружени в шихте обожженных брикетов мышь ка более 0,01 % процесс повтор ют. При нагреве шихты в газовой восстановительной атмосфере в состав смеси ввод т только руду и известн к. Преимуществом описываемого способа вл етс то, что он технологически прост, и получаемый самоплавкий офлюсованный пористый агломерат с выгодой может быть использован в доменных печах.If burnt mouse briquettes are detected in the mixture over 0.01%, the process is repeated. When the mixture is heated in a gas reducing atmosphere, only ore and limestone are introduced into the mixture. The advantage of this method is that it is technologically simple, and the resulting self-melting fluxed porous sinter can be used to advantage in blast furnaces.
