| Abstract: | 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: D960=0.148X+0.005, r= 0.998; D640 = 0.124X-0.003, r=0.999; D710 = 0.127X+0.018, r = 0.994;D795 = 0.261X+0.007, r = 0.999. |
