攀枝花冶金矿山公司选钛厂是该公司最大的钛精矿生产厂,年产能力8万t以上。1990年,该选厂将X射线荧光分析方法及测试装置应用于钛精矿及尾矿样品中的含钛量分析。该方法工作原理是采用来自Fe~(55)放射源的x射线对样品的表面进行照射并用NaI晶体的闪烁探测器记录反射的特征x射线。通过特征x射线的强度,求得样品的含量值。该分析仪器
Panzhihua Metallurgical Mining Company Titanium Dioxide Plant is the company’s largest titanium concentrate production plant with an annual output capacity of 80,000 t or more. In 1990, the mill applied X-ray fluorescence analysis and test equipment to the titanium content analysis of titanium concentrates and tailings samples. The method works by irradiating the surface of a sample with x-rays from Fe ~ (55) radiation sources and recording the reflected characteristic x-rays with a scintillation detector of a NaI crystal. The content of the sample was determined by the intensity of the characteristic x-ray. The analytical instrument
