本文件规定了细粒煤泡沫浮选试验的实验室程序，例如 粒径小于0.5mm。该程序提供了一种评估一般浮选的方法 在一组规定的标准条件下，煤的特性，不一定表明 那煤的全部浮选潜力。 煤的浮选特性对浮选条件的变化很敏感。这些条件 可以通过改变基本参数（如浮选时间、试剂和投加率）来改变。分离 浮选试验用于评估改变这些参数的效果，以确定最佳浮选 特定煤炭的条件。评估浮选响应的方法将在单独的附录中给出 标准交叉引用:ISO 1172ISO 13909-3ISO 13909-4ISO 648ISO 18283ISO 565ISO 1171ISO 13909-1ISO 1213- 1ISO 13909-2ISO 1953购买本文件时提供的所有现行修订均包含在购买本文件中。

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.Cross References:ISO 11722ISO 13909-3ISO 13909-4ISO 648ISO 18283ISO 565ISO 1171ISO 13909-1ISO 1213-1ISO 13909-2ISO 1953All current amendments available at time of purchase are included with the purchase of this document.
