引言矿物浮选过程的工艺因素之一是粒度。浮选时不但要求矿物单体解离,而且要求磨到适宜的粒度。因此研究和测量浮选粒度,是矿物浮选研究者必要工作之一。本文将简述粒度与可浮性的关系,并介绍筛析法,水析法、激光粒度分析法等粒度测量方法。 Introduction One of the process factors in mineral flotation is particle size. Flotation requires not only the dissociation of mineral monomer, but also requires grinding to a suitable particle size. Therefore, the study and measurement of flotation particle size is one of the necessary work of mineral flotation researchers. This article will briefly describe the relationship between particle size and floatability, and introduce particle size measurement methods such as sieve analysis, water analysis, and laser particle size analysis.
