Abstract

The flotation of coking coal after treatment of the coal pulp by microbubbles is investigated. Differential granulometric analysis indicates that, when using air microbubbles, the flotation of small coal particles (<50 μm) predominates. The effectiveness of flotation of small coal fractions (<0.1 mm) by microbubbles, without reagent, is comparable with that attained when using traditional apolar and complex reagents.

浮选前煤表面的微泡改性

摘要

研究了微气泡处理煤浆后焦煤的浮选。差示粒度分析表明，当使用空气微泡时，小煤粒（<50μm）的浮选占主导地位。在不使用试剂的情况下，通过微气泡浮选小颗粒煤（<0.1 mm）的有效性可与使用传统的非极性和复杂试剂相比。
