翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク RTB Bor ： ウィキペディア英語版 RTB Bor RTB Bor (Rudarsko-topioničarski basen Bor) is a copper mining and smelting complex located in Bor, Serbia. ==History== Since the mid-1990s and during the time of sanctions on the Federal Republic of Yugoslavia, production in the RTB Bor dropped significantly from the very prosperous 1970s and 1980s. This has been due to both diminishing reserves and the inability to obtain new equipment that would most efficiently gather the remaining ore no longer of high grade. Copper mining is the key basis of Bor's economy and the effects of decreased production could be seen all over the town. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RTB Bor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
