众所周知,对高炉炼铁而言,铁矿石中的硫、磷、铅、锌、铜是有害杂质,要求其含量不高于硫0.3％、磷0.25％、铅0.1％、锌0.2％、铜0.2％,否则就要采取措施,脱除杂质。但是这些杂质对其它部门却成为有用之物。目前新疆地区三个主要铁矿石皆属多种成分的复合矿石,其中硫0.91～3.48％,远高于标准,此外,还伴生少量铜、铅、钴等有色金属, It is well-known that sulfur, phosphorus, lead, zinc and copper in iron ore are harmful impurities for blast furnace ironmaking, and their content is not higher than 0.3% of sulfur, 0.25% of phosphorus, 0.1% of lead, 0.2% of zinc and 0.2% of copper 0.2%, otherwise we must take measures to remove impurities. But these impurities have become useful to other sectors. At present, the three major iron ores in Xinjiang are all multi-component composite ores, of which sulfur is 0.91 to 3.48%, which is much higher than the standard. In addition, a small amount of non-ferrous metals such as copper,
