针对含锡锌砷超标的铁精矿采用球团直接还原工艺，既获得了供电炉炼钢用的优质金属化球团，又有效地脱除了产品中锻锌砷等杂质，脱除率达到90％以上．达到了国家规定的质量标准要求，是较理想的资源利用方案．
Aiming at the iron ore concentrate containing tin, zinc and arsenic that exceeds the standard, the pellet direct reduction process is used to obtain both the high quality metallized pellets for electric furnace steelmaking and the effective removal of impurities such as wrought zinc and arsenic in the product, with a removal rate of 90 %the above. Reached the national standard of quality requirements, is an ideal resource utilization program.
