研究了贵州赫章镁菱铁矿石的烧失率、含铁量与焙烧温度、焙烧时间和焙烧方式的关系以及镁菱铁矿石在受热时的热爆裂和强度变化 ,为提高贵州赫章镁菱铁矿石的含铁品位 ,使其变为可开采有使用价值的高炉富矿料提供了理论依据
The relationship between loss rate, iron content and calcination temperature, calcination time and roasting method of Hezhang magnesian iron ore in Guizhou Province and thermal burst and strength change of magnesian iron ore during heating were studied. In order to improve the magnetic properties of Guizhou Hezhang maginite ore, The iron-bearing grade of the stone provides a theoretical basis for the conversion of valuable blast furnace ore-rich material
