巴西 Morro do Ouro 金矿位于米纳斯吉拉斯州西北部 Paracatu 镇北1.5Km 处,探明矿石储量7200万 t,品位0.61g/tAu,另有远景矿石储量3800万 t,品位0.6g/tAu。1985年初完成可行性研究。勘探、中间厂试验和工程投资共6700万美元。同年未开始建设,1987年6月竣工,12月开始产金,1988年初达产。预计2003年矿石年产量将达到560万t,金年产量3～3.5t,分别占巴西现在矿石与金总产量的大约4%和20%。
The Morro do Ouro gold mine in Brazil is located 1.5Km north of the town of Paracatu in the northwestern part of Minas Gerais and has a proven ore reserves of 72 million tons and a grade of 0.61 g / tAu. In addition, the prospect ore reserves are 38 million tons and the grade is 0.6 g / tAu. Feasibility study completed in early 1985. Exploration, intermediate plant test and project investment total 67 million US dollars. The same year did not start construction, completed in June 1987, in December began gold, production in early 1988. It is estimated that the annual output of ore in 2003 will reach 5.6 million tons and the annual output will be 3 ~ 3.5 tons, accounting for about 4% and 20% of the total output of ore and gold in Brazil respectively.
