煤泥浮选效果评价方法的研究

Research into Methods of Evaluating Coal Flotation Efficiency

煤泥浮选效果评价是浮选管理的一个重要问题。笔者根据实验和实际资料,对计算原煤效率η_κ、浮选精煤数量指标η_(if)、以及可燃体回收率η_ε三种评定方法进行了对比分析,认为用可燃体回收率η_ε作为评定浮选效果的主要指标较为合理、简便,并提出了相应的评定指标体系。

It is important to evaluate the efficiency of coal flotation processes. On the basis of the laboratory test and practical data, the paper analyzes three evaluation methods for calculating raw coal efficiency ηk, flotation concentration index ηif and combustible material recovery ηε. It is concluded that combustible material recovery ηε is the best one for evaluating coal flotation effects. A system of evaluation indices has also been developed.
