矿石形状对放射性分选探测效率的影响
Influence of Ore Shape on the Efficiency of Radioactive Sorting and Detection
摘要
Abstract
The ore subjected to radioactive sorting treatment is crushed ore,with random shapes,which directly affects the accuracy of ore grade detection.To enhance the accuracy of radioactive sepa-ration detection,standard samples of uranium ore were prepared to conduct an influence test on how the shape of uranium ore affects detection efficiency.The relationship between the ore shape factor and the variation coefficient of detection efficiency was examined,leading to the establishment of a de-tection efficiency correction algorithm based on ore shape.Additionally,a quantification method for ore shape suitable for uranium ore radioactivity detection was proposed.The validity of the proposed detection efficiency correction algorithm has been verified through practical ore sorting tests.After implementing this algorithm,the error in uranium ore grade detection was reduced to less than 5％in over 70％of the test groups.This significantly mitigates the impact of ore shape on detection efficien-cy and enhances the accuracy of uranium ore grade detection.关键词
