초록
In order to estimate the preliminary development feasibility according to the commodity, the content of 9 IT-industrial mineral commoditites (In, Re, Ga, Ge, Se, Te, Y, Eu, Sm) in 68 ore specimens obtained from 34 metallic mines within the so-called the Taebaegsan-Hwanggangri mineralized zone were analyzed. Analytical results are as follows. The ore specimen from northern ore body of the Hongcheon mine contained 233.51 ppm samarium (crustal abundance=0.1 ppm) and 46.78ppm europium (crustal abundance=0.1 ppm), and the ore specimen of the Sangdong mine contained 90.15ppm selenium (crustal abundance=2 ppm). Especially, the detailed investigation on the above-mentioned mines is required due to the high contents of specific mineral. And, in case of gallium content in the Keumcheonji and the Hongcheon mine, and indium content in the Cheongil and the Yeonhwa No. 2 mine, it is required to elastically carry out the revaluation on reopening of mines in terms of the international metal price. On the other hand, in case of germanium, yttrium, tellurium, rhenium, it is thought that there are no mines with the development potential value in this study.
