摘要

利用便携式源激发空气光路多元素Ｘ荧光仪，成功地开发了快速测定铝土矿的Ａｌ２Ｏ３／ＳｉＯ２比及轻元素定量分析应用软件．对铝土矿中的三个主测元素铝、硅、铁所达到的分析合格率分别为１００％、９３％和９７％．本项目对铝土矿矿山的投入／产出比为０．０７５，具有显著的经济效益。论述了校准样品的采集与数学模型的研究开发；针对铝土矿轻元素分析所存在的问题，提出了解决的方法，并介绍了试验研究结果．

Abstract

Based on a portable radioisotope XRF instrument the XRF analysis method for light elementS in bauxite has been developed for the first time in China.It can be used to measure simultaneously elements

such as Al

and the Al/Si ratio.The confidence levels for analyzing Al2O3

SiO2 and Fe2O3 in bauxite are 100%

93% and 97% respectively. Technical difficulties in the analysis of bauxite are indicated and basic concepts and some main test measures for tackling them are put forward.At last

the measurement results are given

and the selection of calibration samples and the asssy model are discussed.
