摘要: 针对长坡锡石多金属硫化矿组成复杂,硫化矿混合浮选时硫酸用量较大,对设备腐蚀严重,污染环境等特点,在不加硫酸的条件下进行了硫化矿混合浮选捕收剂开发试验研究。研究结果表明,高级黄药可以在不加硫酸的条件下浮选硫化矿,但铅锌硫浮选回收率偏低,其中9个碳原子黄药的捕收效果最好;巯基苯丙骈噻唑对铅锌硫的捕收效果比黄药要好;新型捕收剂DT08对硫化矿捕收效果最好,在不加硫酸,硫酸铜用量为100 g/t的条件下,铅、锑和锌的回收率分别达到了87.63%、91.83%和90.98%,比传统药剂制度铅锌锑的回收率分别提高了14.19%、27.22%和5.81%,降低了生产成本,改善了生产环境。

Abstract: In view of the fact that Changpo cassiterite ore containing multi-metal sulfides has a complex composition, requires a high sulfur acid consumption in bulk flotation, causes serious erosion of equipment and environment pollution, test research was carried out on developing a collector for the bulk flotation of sulfide minerals without sulfuric acid. The results indicate that higher xanthate can float sulfide minerals without sulfuric acid but has low recovery of lead-zinc sulfides, with the xanthate with 9 carbon atoms having the best performance. Mercaptobenzothiazole has a better performance than xanthate for collecting lead-zinc sulfides and new collector DT08 has the best collecting effect for sulfides. It can recover 87.63%, 91.83% and 90.98% for lead, antimony and zinc respectively at a copper sulfate dosage of 100g/t without sulfuric acid, being 14.19, 27.22 and 5.81 percentage points higher than those by conventional reagent regime respectively, thus reducing the production cost and improving the production environment
