一、引言 微细粒嵌布矿石的有效利用和开发以及目前选厂中以微粒形式损失的大量金属的有效回收是摆在选矿工作者面前迫切和重要的课题。这个课题包括微细粒矿物的分选和固液分离。 微细粒矿物具有体积小、重量轻、比表面积大等特点。它与水组成的微细粒矿物悬浮体是一粗分散体系,表面力在其体系中起主导作用并带有许多类似于胶体的性质,如分散、聚团等等。在实际分选过程中,我们对
I. INTRODUCTION The effective utilization and development of fine-grained riprap ore and the effective recovery of a large amount of metal that is lost in the form of particulates at the currently selected mill are an urgent and important issue facing mineral processing workers. This topic includes the separation of fine-grained minerals and solid-liquid separation. Microfine minerals with small size, light weight, large surface area and other characteristics. Its finely divided mineral suspension with water is a coarsely dispersed system whose surface forces dominate its system and carry many colloidal-like properties such as dispersion, agglomeration, and the like. In the actual sorting process, we are right
