Comparative characterization of surface roughness of sylvite, spathic salt and carnallite gains in nanorange

The article considers statistical properties of surfaces of sylvite, spathic salt and carnallite grains in nanorange. The authors describe processed experimental data obtained on scanning microprobe Dimension ICON in nanorange for grains of the Upper Kama potassium and potash-magnesium rock salts. Fractal dimension determined by minimum cover method is used as a characteristic of the grain surface roughness. The authors find differences in statistic properties of one-dimension divergent cuts of the grain surfaces.
