摘　　要：针对东林公司选煤厂浮选入料浓度超高,入料粒度细、灰分高的特点,通过试验及调试,对比了复合药剂和HK浮选药剂的浮选效果。结果表明:无论是生产低灰精煤还是高灰精煤,HK浮选药剂效果都明显优于复合药剂,可以生产出灰分为11%~20%的精煤,从而为无烟煤超高浓度浮选提供了借鉴。The flotation circuit of Dongline company of being uxtraordinarily high in pulp density, fine in is treating an anthracite coal which has the features size and high in ash. A comparative test is made on the performance of the composite and HK flotation agents. Test result shows that HK agent is far superior to composite agent in efficiency no matter whetther low-or high-ash concentrate is intended to be pro- duced. With the use of the HK agent, the ash of the concentrate produced is reduced to 11% -20%. This provides a valuable reference for flotation of anthracite in uhrahigh pulo density.
