The pyrolysis and the porosity of natural dolomite are investigated by terahertz time-domain spectroscopy for primary quality control in industry. From terahertz spectra, the transformation of natural dolomite modified by calcination can be clearly differentiated. Based on such results, the thermal active dolomite is studied on adsorbing copper ions in water at first glance. Also, the terahertz maps highlight the subtle variations of the nominal porosity existing in dolomite. In particular, the refractive index and absorption coefficients evidence the variation of mineral properties within natural dolomite. Compared with traditional methods, terahertz time-domain spectroscopy is thus of great significances to gain a non-destructive and contact-free understanding of natural minerals, even in geological studies and environmental industries.
