Quantitative Infrared Spectroscopic Analysis of WolIastonite,CaIcite and Quartz in Ores

Wollastonite, calcite and quartz in ores can be quantitatively determined by measuring the optical densities of the four characteristic absorbance bands at 960, 640, 710 and 795cm-1 of the infrared spectra. The equations and coefficients are as follows: D
