一、概况 我们考察的四个铅锌选厂是:芒特·艾萨矿业有限公司(MIM)2~#选矿厂、电解锌公司(EZC)罗斯贝尔(Rosebery)选矿厂、新布罗肯希尔(NBHC)选矿厂和锌有限公司(Z·C)选矿厂。 这四个选矿厂,也是澳大利亚生产铅锌的主要选矿厂。澳大利亚的铅锌地下资源十分丰富,铅锌矿山工业很发达。自七十年代以来,选矿厂的处理能力不断增加。 芒特·艾萨矿业公司2~#选厂,一九八一年增加了一个重介质选矿车间,使选厂处理能力由8800吨/日提高到14000吨/日。电解锌公司的罗斯贝尔选厂,一九三六年投
I. Overview The four lead-zinc beneficiaries we surveyed are: Mines 2 ~ # Mines, EZC Rosebery Concentrator, New Brockenham NBHC concentrator and Zinc Co. Zinc concentrator. These four beneficiation plants, but also the main lead-zinc production plant in Australia. Australia’s lead-zinc underground resources are very rich, lead-zinc mine industry is well developed. Since the 1970s, the processing power of the concentrator has been continuously increasing. 2 # # mills at Mount Isa Mining Company added a heavy medium beneficiation plant in 1981 to increase the plant’s processing capacity from 8,800 tons / day to 14,000 tons / day.
