Use of a portable X-ray analyser for manganese and iron assay in minerals
Description
The use of a protable X-ray fluorescence analyser for manganese and iron assay in minerals is described. The concentration range in the measured samples was 30% to 60% for Mn and 2% to 20% for Fe. The excitation source used was a 3 mCi 109Cd sealed source. Balanced filters were used for the X-ray analysis. The statistical study of results showed a precision better than 0,5 for Mn, but only 4% for iron. They can be improved either increasing the counting time or using a 238Pu source
