Use of Radioisotope-Excited X-Ray Fluorescence Spectrometry for on-Stream Analysis of Major Elements (Cu, Zn, Pb, Fe) in the Flotation Pulp of Non-Ferrous Ores. Final Report for the Period of 1 November 1975 - 31 October 1976

摘要

On-stream radioisotope-excited x-ray fluorescence analytical systems were developed and applied to the analysis of major elements (Cu, Zn, Pb, Fe) in the flotation pulp of non-ferrous ores. The analytical systems consist of a sampling cell, a 4mCi exp 241 Am excitation source and a Si(Li) detector with an associated 1024 multichannel analyzer all of which are incorporated into an on-stream, closed-circuit slurry installation. Density corrections and matrix effects were considered. It was suggested that higher sensitivities could be obtained by the use of a 10-20mCi exp 241 Am source and optimization of the geometrical efficiency. (Atomindex citation 08:335085)
