在澳大利亚于1981年开采金18吨,到1986年增加到80吨,推测将来可增至150吨。其增长原因是(1)发现了新的地质线索;(2)矿山开采和选矿工作的勘探技术有所提高;(3)澳元贬值;(4)金在美国最低价格稳定;(5)金的纳税章程不同于南非和北美。澳大利亚的金矿床的金品位不高,矿床规模不大,为进一步增长金的开采量,尚需有相应的纳税章程。 In Australia, 18 tons of gold were mined in 1981 and increased to 80 tons in 1986, presumably to 150 tons in the future. The reasons for this increase are: (1) new geological clues have been discovered; (2) the exploration technology for mines exploitation and beneficiation has been raised; (3) the depreciation of the Australian dollar; (4) the lowest gold price stable in the United States; (5) Tax regulations differ from South Africa and North America. Gold deposits in Australia’s gold is not high, the size of the deposit is not large, in order to further increase the amount of gold mining, still need to have the corresponding tax regulations.
