恰姆比希矿业公司已发现的氧化—硫化铜矿储量为35,000,000吨,平均合铜3.37%。矿山从1963年4月开始进行露天开采,以后将同时采用地下开采。公司的湿法炼铜厂已于1965年4月中旬从氧化矿中生产出第一批阴极铜。第一阶段的生产能力为10,000吨,计划在1966年生产26,000吨阴极铜。根据矿石特性,采用以下四种冶炼方法:(1) Cham Bishop Mining Company has found reserves of oxidized-copper sulphide 35,000,000 tons, the average copper 3.37%. The mines opened their mines in April 1963 and will be mined in the future. The company’s wet-process copper mills produced the first cathode copper from oxide mines in mid-April 1965. The first phase has a production capacity of 10,000 tons and plans to produce 26,000 tons of cathode copper in 1966. According to ore characteristics, the following four smelting methods: (1)
