新型药剂体系在某石英脉型萤石矿浮选中的应用

摘要

The content of SiO2and CaCO3were 46.47% and 2.09%, respectively, of the quartz vein type fluorite ore in Henan province, so it was difficult to obtain high quality concentrate by u-sing conventional flotation reagents.The flotation experiment was carried out by using the new low temperature resistant collector FX6A and the combined inhibitor ZY401-1 in this research.The experiment results showed that: the fluorite concentrate could be obtained through the beneficiation process of " grinding-one roughing-one scavenging-six selecting -middling centralized treat-ment", and the concentrate with yield 41.99%, CaF2content 98.91%, recovery rate 94.82%, the harmful components SiO2and CaCO3content with 0.23% and 0.80%, respectively, was ob-tained, and the processing indicators were excellent.The flotation experiment showed that the col-lector FX6A had the advantages of low temperature resistance and high selectivity; the combination inhibitor ZY401-1 had the advantages of strong selective inhibition.%河南某石英脉型萤石矿SiO2含量为46.47%,CaCO3含量为2.09%,采用常规浮选药剂较难获得高品质精矿.采用新型耐低温捕收剂FX6A和组合抑制剂ZY401-1组成的药剂体系对该矿进行了浮选试验.试验结果表明:原矿经"磨矿—一次粗选—一次扫选—六次精选—中矿集中处理"的选矿工艺流程可获得产率为41.99%、CaF2含量98.91%、回收率94.82%、有害组分SiO2和CaCO3含量分别为0.23%和0.80%的精矿产品,选别指标优良.浮选试验表明:该药剂体系的捕收剂FX6A具有耐低温、高选择性等优点;组合抑制剂ZY401-1具有选择性抑制能力强等优点.
