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.
국내 소위 태백산-황강리광화대의 34개 광산의 68개 광석을 대상으로 9개 IT산업용원료광물자원(In, Re, Ga, Ge, Se, Te, Y, Eu, Sm)의 함량을 분석하여 광종별 예비개발타당성을 추정한 결과는 다음과 같다. 홍천광산 북광체 광석시료의 사마륨 함량은 233.51 ppm(지각함량=0.1 ppm)이며, 유로퓸 함량은 46.78 ppm(지각함량=0.1ppm)이다. 그리고, 상동광산 광석시료의 셀레늄 함량은 90.15 ppm(지각함량=2 ppm)이다. 특히, 상기한 광산들에 대해서는 특정광물의 고함량으로 인해 정밀조사가 요구된다. 금천지 및 홍천광산 북광체의 갈륨함량, 청일광산과 제2연화광산의 인듐함량의 경우, 국제금속가격의 추이에 따라 광산의 재가행에 대한 평가가 탄력적으로 수행되는 것이 요구된다. 반면, 게르마늄, 이트륨, 텔루륨, 레늄의 경우, 본 예비연구에서는 경제적으로 개발할 가치가 있는 광산은 없는 것으로 사료된다.
