建成的中央采选公司破碎-选矿联合企业,包括有两个平行的处理磁铁矿(没氧化的)和氧化的含铁石英岩的系统。磁铁矿含铁石英岩的选别含磁铁矿和磁铁矿-碳酸盐-硅酸盐变种的第一、二和四含铁矿层是没有氧化的石英岩,在每个含铁矿层中它们的比例是不同的。各层进入选别时上述各变种所占的比例是:K_2~(1m)=3～5％;K_2~(2m)=50～55％;K_2~(4m)=40～46％。整个矿床的全铁品位是31～33％,其中磁铁矿中的铁占20～26％。矿石中的矿物组成是:磁铁矿占28～33％、石英岩占45～50％、含铁硅酸盐(绿泥石)占
The built-in central mining company Crushing and Dressing Consortium includes two parallel systems that deal with magnetite (non-oxidized) and oxidized ferrous quartzite. Selection of magnetite-bearing quartzite The first, second and fourth iron-bearing formations containing the magnetite and magnetite-carbonate-silicate variants are unoxidised quartzite, Their proportions in the mine are different. Each layer into the selection of the above variants accounted for the ratio is: K_2 ~ (1m) = 3 ~ 5%; K_2 ~ (2m) = 50 ~ 55%; K_2 ~ (4m) = 40 ~ 46%. The total iron grade of the entire deposit is 31-33%, of which iron accounts for 20-26% of the magnetite. The mineral composition of the ore is: magnetite accounts for 28 ~ 33%, quartzite accounts for 45 ~ 50%, ferrous silicate (chlorite)
