1. Introduction
It is necessary for the recovery of the marginal mineral source since mineral sources contribute
extremely the economy of a country. For this reason, there is an increasing trends for the ore analysis
in the mining industry. Ore analysis can be made of various techniques. However, the development
of EDXRF technique has opened new possibilities for ore analysis. The EDXRF technique has many
advantages over the other techniques:
• simultaneous determination of multielements,
• the possibility of determinations in wide concentration range,
• the cheap equipment according to wavelength dispersive X-ray +uorescence, etc.
Since the beginning of application of EDXRF technique as an analytical tool, a great deal of research
has been done in mineralogical and biological materials by diEerent workers.
