巴卡尔矿区碳酸盐铁矿石选矿研究工作的概况冶金工业的发展提出了利用有巨大储量的巴卡尔(Бакал)的碳酸盐铁矿石(菱铁旷)的问题。这些矿石的特点是:组成不均匀,铁的品位低(25～34％),挥发物和氧化镁的含量较高,而在个别地段硫和二氧化硅的含量较高。矿石组成上的特点在很大程度上妨碍了矿石的利用。含铁较高(超过30％)的碳酸盐矿石加在切利亚宾冶金厂的高炉炉料中,但在高炉冶炼时大量焦炭消耗在碳酸盐的分解上。此外,采富矿需要对矿床做选择性的开采。因此在处理碳酸盐矿石时,不仅要用热处理,还得用机械选矿。
OVERVIEW OF THE RESEARCH ON THE CARBONATE IRON ORE MINERALIZATION IN THE BAKARO MINE The development of the metallurgical industry raises the question of the use of the Bakar Бакал carbonate iron ore with great reserves. These ores are characterized by uneven composition, low iron grade (25-34%), high levels of volatiles and magnesia, and higher levels of sulfur and silica in individual sections. The compositional characteristics of the ore largely hindered the utilization of the ore. Carbonate ore with high iron content (more than 30%) is added to the blast furnace charge at the Celliab Metallurgical Plant, but much of the coke consumed during blast furnace smelting is consumed by the decomposition of the carbonate. In addition, ore mining needs to be selectively mined. Therefore, when dealing with carbonate ore, not only to heat treatment, have to use mechanical beneficiation.
