Abstract
DETERMINATION OF COPPER IN WALL-FACE AND DRILL CORES BY X-RAY FLUORESCENCE METHOD
Summary
Portable radioisotope fluorescence analyser employing 238P source and Ni-Co balanced filtres has been used to determine copper in ores of the "Lubin" and "Polkowice" copper mines. Measurements have been made "in situ" of powder ore samples and of solid drill core samples. The results obtained prove a usefulness of the measurements "in situ" in the quick determination of copper in wall face in order to check ore exploitation, and in the case of shales and sandstones - in the fast estimation of reserves. A high accuracy of the laboratory fluorescence analysis of powder samples points to a possibility of decreasing the number of chemical analyses. The fluorescence analysis of drill cores may give the same effects.
