Nonmetallic mineral products study


Nonmetallic mineral products study

Nonmetallic mineral products are usually divided into four groups:
•    Chemical rock material mostly used for fertilizers production;
•    Raw material for metallurgy used for refractory, flux, molding material, for agglomeration of ore fell;
•    Construction materials including nonmetallic construction materials, glass and ceramics raw material, mineral paints, thermal and sound insulation materials, raw material for binding substances;
•    Nonmetallic raw materials including industrial crystals, precious and semiprecious stones, asbestos, talc, graphite and abrasion materials.

X-ray fluorescence analysis is an ideal method for nonmetallic mineral products analysis due to the wide range of determined elements and their concentrations. Almost all nonmetallic mineral products may be analyzed with the method. Short time and high precision of analysis provides composition determination of products involved into production run without stopping the process.

There are two typical ways of sample material preparation for analysis:
- grinding of the sample material to 50 micron particles and pressing pellets;
- fusing the sample material with Borate flux, preparing glass.

Prepared samples are placed in a spectrometer and analyzed. Element contents are calculated with preliminary obtained calibration curves.

X-ray fluorescence analysis with these sample preparation methods provides determination of elements from Na to U in the mass concentration range from 0.001% to 100%.


"SPECTROSCAN MAKC-GVM" WDXRF spectrometer determines elements from Na (Sodium) to U (Uranium) in solids, liquids or powders, in solutions and thin films, deposits on filters.
