| 摘 要： | 介绍了依据煤炭H-R可选性曲线的基本形式绘制煤泥可浮性曲线的步骤:根据煤泥分步释放浮选试验结果,分别绘制出精煤曲线β、尾煤曲线θ、灰分特性曲线λ、产率曲线γ和精煤灰分±0.5%含量曲线ε;在A选煤厂的应用实践表明,该曲线可较好的预测煤泥浮选效果。

| Abstract: | Based on the fundamental forms of HR washability curves,plot steps of coal slime flotability curves introduced;according to the results of coal slime regressive release flotation test,separately plotted the curve of:concentrate β,tailing θ,ash characteristics λ,yield γ,concentrate ash ±0.5%ε;application practice at plant A denoted that flotation performance well predicted by these curves. |
