MINERAL ANALYZING APPARATUS, AND MINERAL ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a mineral analyzing apparatus and a mineral analyzing method that can accurately analyze the proportions of minerals contained in an ore.;SOLUTION: A mineral analyzing apparatus comprises a scanning electron microscope 10 including an energy dispersion type X-ray analyzer 11 and an analyzer unit 20. The analyzer unit 20 specifies mineral regions of mineral particles in a BSE (backscattered electron) image of polished ore pieces, identifies types of minerals on the basis of an EDS (energy dispersive X-ray spectrometry) spectrum of the mineral particles, removes, from the mineral regions, parts whose BSE brightness counts are not above a correction threshold, and figures out ratios of mineral species in the ore from square measures of the mineral regions and the mineral species. It is thereby made possible to exclude, from the mineral regions, the mineral parts embedded under the measurement surface and take into consideration only the measurement surface exposed on the measurement surface. As a result, the square measures of the mineral regions can be accurately figured out, and the proportions of mineral species contained in the ore can be accurately analyzed.;COPYRIGHT: (C)2015,JPO&INPIT
