| description | ► DE radiography for detection/isolation/characterization of trace mineral particles. ► Millions of particles per day can be examined to locate trace minerals. ► Applications: feed/tailing streams for evaluation of separation efficiency, and Exploration drill core analysis, mine planning and resource evaluation.
Procedures are described for the evaluation and isolation of trace mineral particles from sample populations at the ppm level by dual energy rapid scan radiography using an X-ray microtomography instrument (XMT). After calibration of the XMT, the samples are split into narrow size fractions, each size fraction distributed/assembled on projection plates, and then the plates placed in the sample holder of the XMT for irradiation at two energy levels (dual energy analysis). In this way, for example, more than 200,000 particles of 250×150μm in size can be interrogated in less than 1h and the composition of particles containing high density mineral phases estimated. These trace particles can be isolated for 3D analysis by high resolution X-ray microtomography and/or selected for surface characterization using XPS, TOF/SIMS, or other analytical instruments. Rapid scan radiography can be used for the examination of drill core samples, tailings samples, or any other particulate sample containing trace mineral particles. |
