| Abstract: | This paper described the X-ray fluorenscence spectrometer analysis of low and micro content thorium in iron ore dressing products by means of the powder internal standard method. Compared to the conventional chemical analysis, this is more simple and economic, and can meet the requirements of fast and accurate analysis of various products from ore dressing process. Powder sample is mixed with molybdenum used as the internal standard element, and boric acid used as the adhesioe agent, and pressed to 25 mm diameter circular plate,which can be used for analysls. |
