*******年产200万吨球团矿工程节能评估报告 1.2.5 项目产业背景

高炉炼铁的主要原料——铁矿石，一般分为三类，一是天然富矿，不需加工，经破碎筛分成合格块度后可直接入炉冶炼，因此价格较低，另二类是粉矿需造块后才能入炉冶炼，按造块方式不同，分为球团矿和烧结矿。

与烧结矿比较起来，球团矿有下述优点： 1）粒度均匀，高炉透气性好。

2）冷态强度高，在运输和装卸储存时产生粉末少，有利于长途运输和长期贮存。

3）铁份高，堆密度大，有利于增加高炉料柱的有效重量，提高产量降低焦比。

4）还原性好，有利于改善煤气化学能的利用。 5）由于球团生产废气利用率高，因此能耗比烧结要低。

6）由于球团料层透气性好，强度高，粉末少，故烟气含尘量少，球团烟气中原始含尘量为0.6～0.7g/m，而烧结则达2～5g/m。

但与烧结相比球团也有其缺点： 1）在相同产量下投资要比烧结高。

2）要求原料粒度比烧结的细，一般要求—325目粒级必须大于70%，比表面积1500～2000cm/g，而烧结要求—150目粒级在20%以下。

3）烧结机可以充分利用冶金厂内各类含铁废料，如轧钢皮、瓦斯灰，各类污泥，碱性钢渣等。

4）球团在高炉加热还原过程中容易产生体积膨胀，造成高温还原粉化，影响高炉下部透气性，因此一般高炉球团矿在炉料中配比控料在30%左

*******年产200万吨球团矿工程节能评估报告 右，一般不超过65%。

总之选用球团或烧结主要根据矿粉粒度而定，细的矿粉以选用球团为宜，而粒度粗的矿粉则以烧结为宜。

我国铁矿资源的特点是贫矿较多，能直接入炉的富矿占总储量不到5%，因此绝大部分铁矿均需经过选矿，而且随着矿石需求的增加，矿产资源的不足，开采品位日益下降，而为了达到允许的精矿品位和提高回收率，磨矿的细度也愈来愈细，因此采用球团的优越性也愈来愈高。

我国在原料结构上长期偏重于烧结，而忽视球团，因此球团矿的比例严重偏低。

我国球团的发展是从竖炉开始的，由于竖炉投资较低，因此一大批中小型钢铁厂均建设了8m2和10m2的球团竖炉，这种工艺成为球团生产的主流，但球团竖炉的主要缺点是能耗较高，球团的质量较差，单炉生产能力较小，更主要的是竖炉球团只适用于磁铁精矿，不适用于赤铁精矿。 1.2.6 矿产资源情况

秦龙公司在蒙古国拥有伊罗河和图木尔太二个矿区的开采权。 伊罗河矿为接触交代变质铁矿床，分为东、中、西三个矿区。全区总储量33397万吨（工业储量2.3亿吨），其中东矿区储量20488万吨（工业储量1.5亿吨）西矿区储量8528万吨（工业储量0.55亿吨）中矿区储量4381万吨（工业储量0.25亿吨）。

矿石类型大部分是原生磁铁矿，原生磁铁矿石品位含铁36～69%，平均52.30%，含铁品位较高，但含硫较高，达2.4～4.7%。平均含S3.56%。磷平均含量0.27%（0.22～0.96）

矿体位于山顶及山丘或山谷中缓坡地带，矿体露头良好，浮土厚度4～

*******年产200万吨球团矿工程节能评估报告 60m，开采条件良好。

该矿目前已开始投产，主要开采低硫富矿，部分贫矿采用干磁选使含铁达到62%以上，正规的选矿厂正在建设中。

图木尔太铁矿位于伊罗河矿东约50公里，矿石探明储量为2.29亿吨，其中工业储量1.58吨，分为东西二个矿区，东矿储量1.4亿吨其中工业储量1亿吨，西矿区储量0.89亿吨，其中工业储量0.55亿吨。

东矿区平均品位含铁54.18%。西矿区平均含铁品位49.18%。

以上二个矿山合计储量5.63亿吨，其中工业储量3.88亿吨，平均品位在50%左右，而且大部分是磁铁矿，易采、易选，矿石资源是十分理想的。缺点是含硫较高，但通过选矿试验已证明选后精矿可将含S降低到<0.4以下。

1.2.7 气候条件

区域属中温带大陆性季风气候和干旱荒漠草原气候，处于西风带，受强大的蒙古高压控制时间长。气候主要特征是：冬季寒冷漫长风雪少，春季干燥少雨风沙多，夏季干热降雨少，秋季天高气爽霜来早。年平均气温5.1℃，一月平均气温-16.2℃，极端最低气温-29.7℃，七月平均气温25.7℃，极端最高气温39.0℃。结冰期8个月，境内烤火期7个月。年日照时数3356.8小时，日照率76%。霜冻出现早，最早9月末出现，最晚5月末结束，无霜期仅221天左右。雨水分布不均，自南向北、自东向西递减。年降雨量变化大，平均降水量139.5mm（1996年降水量最多256.9mm，2001年降水量最少39.7mm）。常年盛行偏西风，年平均风速4.1m/s。 1.2.8 主要经济指标
