[英刊《矿物工程》报道]加拿大科明科研究院研究了矿物解离度的测定问题。矿物解离是选矿中的基本问题之一,也是流程设计或回路操作条件需要考虑的主要问题。已有许多统计法可以测定包裹矿物的情况,但这些方法需要采用特殊设备,而且所需时间也较长。已研究出一种可以快速确定特定矿物解离度的新方法。该方法采用抛光盘、光学显微镜以及扩展纸。无需为试样制备或颗粒计数 [British Journal of “Mineral Engineering” reported] Kuming Institute of Canada studied the determination of the degree of mineral dissociation. Mineral dissociation is one of the basic problems in mineral processing and is also a major issue that needs to be considered in the design of a process or the operating conditions of a circuit. There are many statistical methods for determining mineral inclusions, but these methods require special equipment and take longer. A new method has been developed that can quickly determine the degree of dissociation of a particular mineral. The method uses polishing discs, optical microscopes, and expanded paper. No need for sample preparation or particle counting
