对低阶烟煤煤泥洗选提质技术的现状进行分析研究后得出，目前的煤泥提质技术已不能满足煤泥提质的要求，需对浮选提质技术进行新的研究.对朔州中煤平朔能源有限公司选煤厂的煤泥进行了可浮性提质试验，得出该煤泥在满足产品质量要求的情况下，浮选可燃体回收率大于80％，煤泥的可浮性为易浮，使得低阶烟煤煤泥浮选成为可能.通过药剂选择性试验，得出 HZ－1浮选药剂更加适合煤泥浮选需要，煤泥浮选的工业生产实践表明，在满足产品质量要求的前提下，浮选完善指标为43.85％，同实验室结果相近，取得了理想的提质效果.

According to analytical study current situation of upgrading technologies on low-rank soft coal slime flotation,the current upgrading technologies could not meet coal quality re-quirements which need conduct new studies about flotation upgrading technologies. Basing upon the floatability of coal slim upgrading experiment in coal preparation plant of ChinaCoal Pingshuo Group Co.,Ltd.,the authors found that when the coal slime meet coal quality requirements,re-covery rate of flotation combustible was more than 80%,floatability of coal slime was easy float-ing which made low-rank soft coal slim flotation possible;according to agent selective test,HZ-1 ,flotation agent was more suitable for coal slime flotation requirement,industrial production practice of coal slime flotation showed that complex index of flotation was 43.85% on the premise of meet the requirements of product quality,and the results were similar in same laboratory which had the ideal upgrading effects.
