Abstract
PROCEDURE FOR ANALYSING ORE BLOCKS The invention concerns a procedure for analysing ore blocks wherein the ore blocks (5) are irradiated in order to determine the precious mineral contents in the surface of the blocks for sorting. The energies of the radiation sources have been so selected that with their aid is excited in the block (5) x-ray fluorescence radiation and Compton-scattered radiation, their intensities being measured with a detector (4). From the ratio of the radiation intensities a characteristic value is gained which characterizes the contents of precious minerals in the surface of the blocks (5) and which may be applied as a sorting criterion.
