The suitable methods to the determination of the trace elements in accessory minerals

Popis výsledku v původním jazyce

The paper presents the comparison of the three following methods: 1) method of proportionate semi-quantitative micro-analysis of heavy metals in minerals, slag and ores (original method - PSA); 2) method of X-ray powder diffraction - XRD and 3) method ofinductively coupled plasma mass spectroscopy - ICP-MS. Original PSA method consists of two steps: a) average composition of the basic powder samples establishment and b) chemical analyses of micro-particles in accessory minerals assessment; the contentsof elements in these particles have higher atomic numbers than the basic powder samples have. The proportionate amount (in g/t) of the separated powder micro-particles of accessory minerals is estimated. To the comparison were chosen the samples of ironore from the mine Tereza in region Staré Ransko. The results determined by PSA method, e.g. the chemical content (trace amount) of elements in accessory minerals were verified by methods XRD and ICP-MS. It was found out that the original
