摘要
对硫铁矿烧渣用作炼铁原料方面的研究进展进行了总结及简要评述,分析比较了从烧渣中分选铁精粉的几种不同工艺,指出采用硫精砂制酸后的烧渣及硫铁矿制酸调整工艺后排放的黑色烧渣为原料炼铁是当前的发展趋势,由硫铁矿烧渣制得的铁精粉的脱除硫砷等杂质的工艺技术研究有待进一步深入。
In the paper,progress on research of utilizing pyrite cinder as raw materials for iron-making is summarized and briefly commented,and several different technologies for recovering iron concentrate from pyrite cinder are also compared.Currently,cinder from production of acid with pyrite concentrate and black cinder from its modified process have been a development trend and the technology for removing impurities such as sulfur and arsenic in iron concentrate powder produced from pyrite cinder is to be further improved.
