标准摘要
[中文适用范围]： 本文件规定了粉煤（例如颗粒尺寸小于 0.5 毫米的煤）泡沫浮选测试的实验室程序。 该程序提供了一种在一组指定标准条件下评估煤的一般浮选特性的方法，但不一定表明该煤的全部浮选潜力。 煤的浮选特性对浮选条件的变化很敏感。 这些条件可以通过改变浮选时间、试剂和剂量率等基本参数来改变。 单独的浮选试验用于评估改变这些参数的效果，以确定特定煤炭的最佳浮选条件。 评估浮选响应的方法将在单独的标准中给出。 [外文原描述]： This document sets out a laboratory procedure for the froth flotation testing of fine coal, e.g. coal of particle size less than 0,5 mm. The procedure provides a means of evaluating the general flotation characteristics of a coal under a set of specified standard conditions, and will not necessarily indicate the full flotation potential of that coal. The flotation characteristics of coals are sensitive to changes in flotation conditions. These conditions can be changed by varying basic parameters such as flotation time, reagent and dosage rate. Separate flotation tests are used to assess the effect of varying these parameters to determine the best flotation conditions for a particular coal. A method of evaluating flotation response will be given in a separate standard.
