摘要 以六偏磷酸钠、苛性淀粉为调整剂,DEK为新型阳离子反浮选捕收剂,对鞍山某铁矿选矿厂磁选铁精矿进行了反浮选工艺研究。结果表明,以DEK为核心的阳离子反浮选药剂体系与原阴离子反浮选药剂体系相比,药剂制度明显简化,可在中性环境下浮选,浮选无需蒸汽加温至30℃左右;采用试验确定的流程和药剂制度处理该磁选铁精矿,可获得铁品位为66.02%、回收率为90.16%的最终铁精矿。 Using sodium hexametaphosphate and caustic starch as regulators, and DEK, a new cationic agent, as col- lector for reverse flotation, the reverse flotation of magnetic separation iron concentrate from an iron ore concentrator in Ans- han were studied. The results showed that, compared with the original anionic reagent system of reverse flotation,the cation- ic reagent system of reverse flotation, which using DEK as the core,was significantly simplified. Flotation could be operated in neutral environment and did not need steam heating to about 30℃. Using the determined process and regulation of agent to deal with the ore,iron concentrate with Fe grade of 66.02% and recovery of 90. 16% was obtained.
