广西八一锰矿矿石的特点是含锰低(18～20%)、含铁高(8～10%)、粉矿比例大(50～0毫米矿石中,小于5毫米的占50%左右)的堆积氧化锰矿矿石。这种矿石必须经过选矿处理方能满足冶炼要求为高速发展我国的钢铁工业提供合格原料。该矿石磁化焙烧的作用是将其中的Fe_2O_3转化为Fe_3O_4,以便于用弱磁场磁选机将其选出,达到提高锰品位和锰铁比的目的。广西八一锰矿的堆积贫氧化锰矿石的处理,过去有许多单位进行过大量的试验工作,取得了一定的成绩。特别是对该矿石用煤气作为
Guangxi Bayi manganese ore is characterized by low manganese content (18-20%), high iron content (8-10%), large proportion of fines (about 50% less than 5mm in 50-0mm ore) Accumulation of manganese oxide ore. This ore must be beneficiated to meet the metallurgical processing requirements for the rapid development of China’s steel industry to provide qualified raw materials. The role of the ore magnetization roasting is to convert one of the Fe_2O_3 into Fe_3O_4 so that it can be selected with a weak magnetic field magnetic separator so as to improve the grade of manganese and the ratio of ferromanganese. Guangxi Bayi manganese ore piling lean manganese ore processing, in the past many units have conducted a large number of tests, and achieved some success. Especially for the ore as gas
