Determination of tin in cassiterite ores and tailings by 241Am source X-ray fluorescence spectrometry

A rapid and precise method was used for the determination of tin in cassiterite ore and tailings from the tin province of Jos Plateau, Nigeria using 241Am isotopic X-ray source. The application of the method is very attractive when compared to solution methods of analysis. Concentration of the ore samples vary from 60 to 78% while the tailings have concentrations of tin from 0.5 to 1.7%.
