The benefited high quality burden is the basis for intensifing blast furnaces operation. "The benefited high quality burden" means the burden having following specialities, namely: high-grade, stability, heat-prepared, uniformity, smallness and free from fines. A high iron content of the burden is a necessary term for raising productivity and lowering coke consumption. In order to obtain high-grade sinters and pellets with proper stability in composition, high iron content, lower ferrous oxide content, higher strength, close size range and less fines, it is necessary to take efficient measures, such as fine-grinding and having it well beneficiated, improving the mixing and blending of the raw materials, choosing the proper size range of sinters, properly decreasing fuel consumption and making up good proportion of high basicity sinter and low basicity pellet, apart from careful operation and strict control of the agglomeration. Moreover, it is also necessary to have the more powerful agglomerating equipment and automatic control of agglomerating process; these can not only save man power, but also provide reliable means for achieving good quality and high production.

精料是高炉强化的基础.精料的内容可以概括为"高、稳、熟、小、匀、净"六个字.提高含铁品位是增产节焦的前提,也是精料的基础.要获得成分稳定、品位高、氧化亚铁低、强度好、粒度均匀、粉末少的优质烧结矿和球团矿,除了对造块过程本身进行精心的操作和严密的控制外,还必须采取一系列措施:如注意铁矿的细磨深选;加强原料时混匀中和;进行烧结矿的整粒;降低燃料用量以及生产高碱度烧结矿和低碱度球团矿搭配使用等都是行之有效的方法.另一方面,造块设备的大型化和生产过程的自动控制和调节,不仅节省人力而且为产品的优质高产提供了可靠的手段.

本文以酸化硅酸钠和酸化硅酸钠加铁盐作为分散剂,对常见脉石矿物石英的微细颗粒在PH为10.5的碳酸钠溶液中的分散稳定性进行了试验研究,发现上述两种分散剂都比单独硅酸钠本身的分散作用强,浮选精矿的品位高;认为其作用机理是在实验条件下所形成的亲水性胶体对细粒石英的分散起了保护胶体的作用。细粒脉石矿物的稳定分散,有利于赤铁矿矿石阴离子捕收剂的浮选。
