A photo-electric spectrophotometer was used to provide a simple, convenient, and accurate method of measuring the refl ectivity of powdered minerals.
The determination of spectral reflectivity of mineral powders provides a useful aid in the identification and chromaticity specification of minerals.
The powdered minerals were used as samples. in the measurements to eliminate the effects of specular reflection, Beilby layer, etc. on the polished surface.
The determination were carried out for the powders of pure galena, sphalerite, pyrite, chalcopyrite, bornite, enargite, stibnite, magnetite, specularite, ilmenite, and quartz in the range of wave length of 380 to 800 mμ.
The chromaticity of the samples based on the C. I. E. system were given, the three standard sources, A, B, and C, being used.
