顺序评价试验方法及其应用

Discussion on the test methods and the application of sequential evaluation

对ISO 8858-2《硬煤-浮选试验第2部分:顺序评价》试验方法中的试验条件、试验流程、操作方法与试验步骤进行了简单介绍,指出该试验方法可用于获得浮选理论指标,是代替小浮沉的最佳选择。通过分析和对比3个煤样的试验结果,表明了顺序评价方法的科学性和实用性。

The ISO standard Hard coal - Froth flotation testing - Part 2 ： Sequential evaluation （ISO 8858 - 2） was briefly introduced in this paper, especially in the aspects of test conditions, procedure, operating method and program. It was indicated that the testing method could be applied to obtain the theoretic flotation indexes, which would be the best choice for substitution of original laboratory flotation. Though the analysis and comparison of the experimental data with 3 coal samples, it was showed that the testing method was scientific and practical.
