摘　　要：刚果民主共和国腾克丰古鲁梅(Tenke Fungurume)铜钴矿山是世界上现有的最大的铜钴矿山,它具有世界上最丰富的铜钴资源。现有的矿石储量可能超过1.19亿t,其中含2.64%铜和0.35%钴。矿山采用常规的露天开采方法。平均每天开采4.65万t物料,其中7000t高品位矿石、7500t低品位矿石和32000t废石。选矿厂日处理矿石7000t,年产11.1万t铜和8545t钴(氢氧化钴)。选矿流程包括磨矿、硫酸浸出和对流倾析、中和、溶剂萃取/电积和钴的回收。矿山和选矿厂基本投资为17.50亿美元,矿石的采矿和选矿总成本为85.10美元/t矿石。The DRC Tenke Fugurume Copper-Cobalt Miner is the word＇s most present copper and cobalt mine. It is believed to hold one of the richest and extensive high grade copper and resources. The ore reserves approximate 119 million tons at average ore grades of 2.64% copper and 0.35% cobalt. The ores are mined with typical open pit miming method. The average daily mining rate will be 46,500 tpd over the mine life. Ore deliveries to the highgrade stockpiles will be 7,000 tpd, low-grade ore production will average 7,500 tpd and waste production will average 32,000 tpd. 7000 t/d ores are delivered to the process plant. 111000 t/a are produced of copper cathode. 8545t/a contained in a hydroxide are produced as the commercial production target. The ore processing flowsheet consists of semi autogenous grinding, sulphuric acid leaching, counter current decantation, neutralization, solvent extraction/eleetrowinning and cobalt recovery. The capital cost of mining and processing plant is 1750 million US $. The operation cost of mining and processing is 81.50 US/t ore.
