一、前言由于炼铁技术不断的发展,高炉对铁精矿品位的要求越来越高,实践证明,提高铁精矿品位是使高炉优质高产低消耗的有效途径之一。如果入炉的铁精矿品位提高1%,则炼铁的焦比可下降2%,高炉的利用系数则可提高3%。因此,近年来不少国家都在努力寻求新的选矿工艺流程,研制高效率的精选设备,以期提高铁精矿品位。例如,在磁铁矿选矿方
I. Preface Due to the continuous development of ironmaking technology, blast furnaces have higher and higher requirements on the grade of iron concentrates. Practice has proved that raising the grade of iron concentrates is one of the effective ways to make high-quality and low-consumption high-quality blast furnaces. If the grade of iron concentrate added to the furnace increases by 1%, the coke ratio of ironmaking can be reduced by 2% and the utilization factor of blast furnace can be increased by 3%. Therefore, in recent years, many countries are struggling to find new beneficiation process and to develop highly efficient selected equipment in order to improve the quality of iron concentrates. For example, in the magnetite dressing side
