Abstract. By means of a simple cadmium sulfide photoconductive cell, the spectral reflectivities of about 200 opaque ore minerals, mostly oriented, have been determined in air at wavelengths of about 470 mmu (blue), 520 mmu (green), 575 mmu (yellow), 600 mmu (orange), 700 mmu (red), and in white light ( approximately 610 mmu ).

Relating the Mineralogical Characteristics of Tampakan …

The mineralogical characteristics of enargite-bearing copper ores from the Tampakan deposit have been investigated as the means to understanding the separation of enargite from other copper sulphides (chalcopyrite and bornite). It was found that a separation of these minerals was possible after grinding the ore samples to a P80 of 90 microns; enargite tends to be ground more readily than the ...
