摘要
系高硫多金属硫化矿床的西盟县新厂铅锌矿，采用常规的单一石灰作抑制剂，不仅铅锌、硫的分选指标很差，而且附属设备复杂。针对此，昆明冶金研究院开发了Ｋ－７＃抑制剂。它与石灰配合使用能有效地抑制黄铁矿，在试验室和生产实践中均获得理想的技术经济指标。
The Xinchang Pb/Zn mine of Ximeng Tin Mines is a polymetallic sulphide deposit with high content of pyrite. Using lime as depressor, not only flotation separation of galena, sphalerite or pyrite from the two others was very poor, but also reagent preparation and addition were quite complicated. Kunming Metallurgy Research Institute has developed Depressor K-7 which can be used together with lime to depress pyrite effectively. Satisfactory metallurgy and economy have been achieved at laboratory and in commercial operation.
