摘要
对浮游选煤精选作业工艺效果评定方法进行学术性探讨,初步提出将精选完善指标作为主要评价指标,浮选精煤可燃体回收率和浮选精煤非可燃体脱除率作为辅助评价指标。依据数理统计分析,在一定条件下,精选完善指标和浮选精煤相对降灰率存在良好的正相关关系。
Method of process performance evaluation on coal cleaning by flotation is discussed,proposed main evaluation index using cleaning perfect index and auxiliary ones using recovery of combustibles and removal of non- combustibles in flotation concentrate. Based on mathematical statistic analysis,better positive correlation between cleaning perfect index and relative ash removal of flotation concentrate occurs under a certain condition.
