赞比亚的大规模铜矿开采业始于本世纪20年代末,其后40年获得稳步发展,至1969年臻于鼎盛,精铜产量创最高纪录,达74.75万吨;但此后生产呈下降趋势,1970年9月,莫弗利纳矿发生大涌水,持续影响该矿的生产能力,赞比亚铜矿床的物理特性对生产也是不利的。出矿品位,已从30年代的4～5％Cu下降到今天的2％Cu左右。许多 Zambia’s large-scale mining of copper began in the late 1920s and then steadily progressed in 40 years to its peak in 1969. The output of refined copper hit a record high of 747,500 tons. However, production declined afterwards, In September 1970, a large influx of water from the Muflina mine continued to affect the mine’s production capacity. The physical properties of the Zambian copper deposit were also detrimental to production. The ore grade has dropped from 4% -5% Cu in the 1930s to about 2% Cu today. a lot of
