Excited x-rays identify minerals as ore moves down conveyor belt [electronic resource] / R.H. Goodman, A.H. Bettens & C.A. Josling, Mineral Sciences Division. Ottawa : Queen's Printer, 1966. p. 43-45 : chart, ill. Reprint series ; RS 7 Cover title. "Reprinted from Canadian Electronics Engineering, June, 1966." Historical publication digitized from print 2017 [by Natural Resources Canada]. "In the uranium mining industry, the presence of uranium ore can be detected through its natural radioactivity but there are few techniques which allow detection of non-radioactive elements. An electronic ore-sorting system using X-ray fluorescence has been developed at the Department of Mines and Technical Surveys, Ottawa, to allow the extension of sorting techniques to other minerals. This system operates on ore sizes from 2 to 10 inches. Rejection of waste material before much effort has been spent in processing means that for a given grinding capacity and reagent quantity, a greater output of final product can be obtained"--p. 43. gccst Minerals gccst Detection Bettens, A.
