用廻转窑富集铅锌矿或含铅锌残渣中的铅锌为世界各国所应用。我国某矿矿石主要是由石灰岩所组成,具有较高的熔点,按理是适于用廻转窑处理的。试验结果证明:这种氧化铅锌矿完全可以用廻转窑来富集铅锌,当地所产的煤可以用作还原剂,结窑现象虽难以完全消灭,但是从试验结果看来可以肯定,在生产实践里当生产操作人员掌握了操作特性及其操作规律后,结窑是可以减少至很轻程度而能顺利进行生产。一、原料性质铅锌矿石基本上可分为原生矿及氧化矿两种。根据矿石鉴定结果,岩石主要为石灰岩。脉石矿物主要为
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 enriched with lead and zinc by rotary kiln. The locally produced coal can be used as a reducing agent, although the phenomenon of junction kiln can not be completely eliminated, but the test results may be affirmative, In production practice, when the production operator grasps operational characteristics and operating rules, the knot kiln can be reduced to a very light degree and can be smoothly produced. First, the nature of raw materials Lead-zinc ore can be divided into two kinds of primary ore and oxide ore. According to ore identification results, the rock is mainly limestone. The gangue minerals are mainly
