米申(Mission)公司系按保证高效率生产来建造的。公司投产初期设备生产能力为1.5万短吨/d(1短吨=0.907t),后来设计能力扩大到2.25万短吨/d。但生产指标通常都大大超过设计标准。据米申矿山公司经理 B.马隆说:在80年代出现困难时期以前,米申公司雇员近1000人,但是1988年初,公司大量减员,减至360人。据阿萨科矿山公司(Asarco)西南矿山部总经理 T.斯卡塔奇尼说,米申公司扩建工程可望于1988年1月完成。工程估算投资 Mission is built on the promise of efficient production. The initial production capacity of the company was 15,000 short tons / d (1 short ton = 0.907t) and its design capacity was expanded to 22,500 short tons per day. However, production metrics often exceed design standards. According to M. Malone, manager of Mishin Mining, there were nearly 1,000 employees in Mishin before the difficult times of the 1980s. However, in early 1988, the company reduced the number of employees to 360. According to T. Scatcicini, general manager of the southwestern mine at Asarco, the expansion of Mission Company is expected to be completed by January 1988. Project Estimation Investment
