英文名称：Hard coal — Froth flotation testing — Part 2: Sequential evaluation

标准范围

ISO 8858-2:2004规定了细粒煤（例如粒径小于0.5mm的煤）泡沫浮选试验的实验室顺序程序。该程序提供了一种评估煤的浮选特性（以产率/灰分关系表示）的方法，这些特性可能来自泡沫浮选过程。未经加热或化学添加剂不能脱水的纸浆样品不包括在ISO 8858的本部分中；它也不包括浮选动力学的调查程序。该试验的目的不是提供电厂设计数据。

ISO 8858-2:2004 sets out a laboratory sequential procedure for the froth flotation testing of fine coal, e.g. coal having a particle size of less than 0,5 mm. The procedure provides a means of evaluating for a coal the flotation characteristics (expressed as a yield/ash relationship) that may be expected from the froth flotation process.Pulp samples that cannot be dewatered without the use of heat or chemical additives are not covered by this part of ISO 8858; nor does it cover procedures for the investigation of flotation kinetics.The test is not intended to provide plant design data.
