在开展对铀矿床物质成分及矿床成因的研究工作中,需提取一定数量的纯沥青轴矿,供单矿物化学全分析、X 光衍射分析同位素年龄测定、差热分析、热重分析等使用,但分离单矿物费工费时,尤其对小于0.10毫米粒级,常因不易提纯而被丟弃。我们在工作中采用 WCF-2型多用磁性分析仪(北京地质仪器厂制)分离、提纯沥青铀矿取得较好的效果。沥青铀矿单矿物纯度达99%以上,每小时平均可提取纯单矿物0.5—1.0
In carrying out research on the composition of uranium deposits and the genesis of the deposit, a certain amount of pure bitumen shaft ore needs to be extracted for full chemical analysis of single minerals, X-ray diffraction analysis of isotopic age, differential thermal analysis, thermogravimetric analysis, etc., However, the time-consuming separation of single mineral waste, especially for less than 0.10 mm size, often because of not easy purification and discarded. We use the WCF-2 multi-purpose magnetic analyzer (Beijing Geological Instrument Factory system) separation and purification of uranium ore to obtain better results. Asphalt uranium single mineral purity of 99% or more, the average per hour can be extracted pure single mineral 0.5-1.0
