Abstract

In order to estimate the preliminary development feasibility according to the commodity, the content of 8 strategic metallic commoditites(Pb, Zn, Cu, Fe, Mo, W, Au, U) in 68 ore specimens obtained from 34 metallic mines within the Taebaegsan-Hwanggangri mineralized zone were analyzed. Analytical results are as follows. The ore specimen of Sangdong mine contained 23% copper(cut-off grade=0.7%) and those of Cheongil and Samhwanghak mines contained average 5% zinc(cut-off grade=2.0%). Especially, the detailed investigation on the above-mentioned mines is required. And, in case of molybdenum(cut-off grade=0.02%) content in Yeonhwa No. 2(0.04%) and Hong-cheon mine(0.02%), and lead(cut-off grade=0.58%) content in Wongasa mine(0.70%), and gold(cut-off grade=10ppm) content in Dongmyoung(279ppm) and Samhwanghak mine(251ppm), 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 uranium, iron and tungsten, it is thought that there are no mines with the development potential value in this study.

태백산-황강리광화대내 34개 광산의 광석을 대상으로 8개 전략광물자원(Pb, Zn, Cu, Fe, Mo, W Au, U)의 함량을 분석하여 광종별 예비개발타당성을 추정한 결과는 다음과 같다. 동의 경우, 상동광산은 23%의 동(한계품위=0.7%)을 함유하는 것으로 나타났으며, 아연의 경우, 청일광산과 삼황학광산은 평균 5%의 아연(한계품위=2.0%)을 함유하는 것으로 나타났다. 특히, 상기 광산들에 대해서는 추가정밀조사가 요구된다. 또한, 몰리브덴의 경우(한계품위=0.02%), 제2연화(0.04%) 및 홍천광산(0.02%), 연의 경우(한계품위=0.58%), 원가사 광산(0.70%), 금의 경우(한계품위=10ppm), 동명(279ppm)및 삼황학광산(251ppm)에서, 각각 해당광종에 대한 국제가격추이에 맞추어 탄력적으로 재가행 여부에 대한 평가가 요구된다. 반면, 우라늄, 철, 텅스텐의 경우, 본 연구결과 경제적으로 개발할 가치가 있는 광산이 없는 것으로 사료된다.
