阿腊沙烧绿石矿床是世界上已知铌储量最大的矿山,占世界上可以经济开采的已知储量的70%以上。该矿山于六十年代初由巴西冶金矿产公司(CBMM)开采。最近15年来,该矿提供的铌占西方世界总耗量的60%以上。基本情况该矿山位于米纳斯吉拉斯州的阿腊沙城南6公里处,矿体座落在阿腊沙碳酸盐杂岩上。巴西著名的地质学家贾尔马·季玛拉斯教授于1954年首次在这里的碳酸岩中鉴别出烧绿 The Arracel pyrochlore deposit is the world’s largest known mine for niobium, accounting for over 70% of the world’s known economically exploitable reserves. The mine was mined by the Brazilian Metallurgy and Minerals Company (CBMM) in the early 1960s. Niobium from the mine has accounted for more than 60% of the total Western world consumption in the last 15 years. The mine is located 6 kilometers south of the city of Aracea, Minas Gerais, and the ore body is located on the Araula carbonate complex. Professor Jalma Quartermalas, a famous geologist in Brazil, identified the burning green in the carbonate rocks here for the first time in 1954
