在选矿厂,对选矿过程的基本控制,其产品分析常常需要好几种方法。在十年前,大多数选矿厂,对每种产品8小时或者24小时的混合样品,均用湿式化学分析来测定其有价金属。因其分析效率差,在取样后得到分析数据大约要一天,其用途是有限的。工厂若采用X射线谱仪,其分析时间则大为缩短,这就可以实现对选厂的产品经常取样,例如每小时取一次样。其取样分析不超过20分钟,在分析的
In the concentrator, the basic control of the beneficiation process, the product analysis often need several ways. Ten years ago, most concentrators used wet chemical analysis to determine their valence for mixed samples of 8 hours or 24 hours for each product. Because of its poor analytical efficiency, it takes about a day to obtain analytical data after sampling, and its use is limited. The factory’s X-ray spectrometer, the analysis time is greatly reduced, which can be achieved on the factory sampling products, such as taking samples once every hour. Its sampling analysis does not exceed 20 minutes in the analysis
