用廻轉窑富集鉛鋅矿或含鉛鋅残渣中的鉛鋅为世界各国所应用。我国某矿矿石主要是由石灰岩所組成,具有較高的熔点,按理是适于用廻轉窑处理的。試驗結果証明:这种氧化鉛鋅矿完全可以用迴轉窑来富集鉛鋅,当地所产的煤可以用作还原剂,結窑现象虽难以完全消灭,但是从試驗結果看来可以肯定,在生产实践里当生产操作人員掌握了操作特性及其操作规律后,結窑是可以減少至很輕程度而能順利进行生产。原料性质
Use 迴 rotary kiln enrich lead-zinc mine or lead-zinc residue in the world for the application of lead and zinc. China’s ore is mainly composed of limestone, with a higher melting point, reasonably suitable for the use of rotary kiln processing. The test results show that the lead-zinc oxide ore can be completely enriched with lead and zinc by a rotary kiln. The locally produced coal can be used as a reducing agent. Although the phenomenon of junction kiln can not be completely eliminated, it seems certain from the test results. Production practice, when the production operator mastered the operating characteristics and operating rules, knot kiln can be reduced to a very light degree and can successfully carry out the production. The nature of raw materials
