摘要
酒钢选矿厂采用阳离子反浮选工艺对焙烧磁选系统进行了提质降杂改造。生产实践表明,该工艺脱硅效果好,药剂制度简单,不用加温,水路不结垢,生产顺行。与原有单一磁选工艺相比,精矿品位提高4.04个百分点,S iO2含量降低4.74个百分点,从选矿至炼铁,每年可降低成本9 525万元。
The cationic inverse flotation techniques on the roasting - magnetic separation system is adopted to improve quality and reduce impurities in dressing plant of Jiusteel. The practices show that this technique has such advantages as good efficiency on removing silicon, simple reagents system, never heating, no fouling and smooth production. Compared with the original single magnetic separation technique, this one can improve the grade of concentrates by 4.04%, and reduce SiO2 contents by 4.74%. From separation to iron - making, about 92.25 million yuan at costs can be saved per year.
