大宝山铁矿是以褐铁矿为主的多金属矿床,其中,铁50～55％,铜0.18～0.26％,砷0.1～0.2％,SiO_25～11％,CaO0.5～1.0％,另含有少量的铅锌及稀有金属。该铁矿含铁品位高,但铜、砷含量均已超过炼铁允许限度,因此作为炼铁原料,必先经脱杂,方能入高炉冶炼。有关单位对该矿曾进行一些氯化挥发脱杂的研究,亦用竖炉,烧结机及回转窑进行过扩大试验。 The Baobaoshan Iron Mine is a limonite-based polymetallic deposit, in which iron is 50-55%, copper is 0.18-0.26%, arsenic is 0.1-0.2%, SiO25-11% and CaO is 0.5-1.0%, and the other contains A small amount of lead, zinc and rare metals. The iron ore high iron content, but the copper, arsenic content have exceeded the allowable limit of ironmaking, so as ironmaking raw materials, must be first unheeded, can only enter the blast furnace smelting. Relevant units of the mine had some chlorination volatile decontamination research, also used shaft furnace, sintering machine and rotary kiln have been expanded test.
