含锡、锌的复杂铁矿石通常难以开采，在中国尚未得到有效利用。研究了含锡、含锌铁矿石的工艺矿物学特征及CO对铁、锡、锌氧化物的还原行为。初步开发了从复杂铁矿中分离锡锌的选择性还原焙烧工艺。在此条件下，铁球团中锡和锌被有效脱除，焙烧后的铁球团可作为大型高炉的优质炼铁炉料。
Tin, zinc bearing complex iron ores are typically intractable and have not been efficiently utilised in China. In this investigation, the process mineralogy of the tin, zinc bearing iron ores and reduction behaviours of iron, tin and zinc oxides by CO were investigated. A selective reduction roasting process was initially developed to separate tin and zinc from the complex iron ores. Under optimum conditions, most of the tin and zinc were effectively removed from the iron ore pellets, and the roasted pellets could be used as high quality ironmaking burdens for large scale blast furnaces.
