1.前言物相分析,是矿石分析的一个组成部分,它的任务是测定元素在矿石中的存在状态及其含量,有人把它叫做化学合理分析。我们要对矿床进行准确的评价和确定合理的选冶流程,不仅与我们所要提取的元素的绝对含量有关,而且与该元素的存在状态有着极其密切的关系。因为由同一元素组成的不同矿物,在工业处理上的难易程序和方法是不同的,所付出的经济代价也不相同,所以由该元素所组成的不同矿物是否能够全部被提取和利用率的大小也不相同,这就要求
1. Foreword Phase analysis, is an integral part of ore analysis, its task is to determine the presence of elements in the ore and its content, some people call it a chemical analysis. We want to accurately evaluate the deposit and determine a reasonable selection and smelting process, not only with the absolute content of the elements we want to extract the relevant, but also with the existence of the element has a very close relationship. Because different minerals composed of the same element have different industrial processes and methods and different economic costs, different minerals composed of this element can be completely extracted and utilized The size is not the same, which requires
