一、前言回顾中龙选矿厂的经历是令人寻味的。1971—1975年完成了以大型基建工程为中心的各工序设备能力的扩大,原矿处理能力计划由1500吨/日增加到1700吨/日,最终实现了2000吨/日,但在80年代初日元汇率急剧变化,经济形势恶劣以及由于金属价格长期低落引起了有色金属矿业萧条。因此狠抓各种措施,紧缩生产费用,节省劳力,节约能源,降低生产成本,尽力摆脱经济困境成了这一时期的重要工
First, the preface Review Long processing plant experience is interesting. From 1971 to 1975, the capacity of each process equipment centering on large-scale infrastructural projects was expanded. The raw ore handling capacity plan was increased from 1,500 t / d to 1,700 t / d and finally reached 2,000 t / d. However, in the early 1980s, The drastic changes in the exchange rate, the bad economic situation and the non-ferrous metal mining slump caused by the long-term drop in metal prices. Therefore, pay close attention to various measures to tighten production costs, save labor, save energy, reduce production costs, try to get out of economic hardship has become an important work during this period
