寿王坟铜矿选矿厂是国家“一五”计划期间建成投产的年处理矿石百万吨的大型有色金属选矿厂,采用先浮选铜,其尾矿再磁选铁的工艺流程。从1957年4月1日投产至今走过了42年的历程,在42年的沧桑变化中,铜原矿品位由1.175%降至0.25%左右,副产品铁原矿品位由30%降至16~17%,年处理矿量由140万吨降至75万吨,铜金属产量由最高3000吨/年降至1225吨/年。副产品铁精矿由25万吨/年降
Shouwangfen Copper Ore Concentrator is a large-scale non-ferrous metal concentrator that treats 1 million tons of ore ore processed and put into operation during the National First Five-year Plan period. It adopts the process of first flotation of copper and re-ironing of tailings. Since it was put into production on April 1, 1957, it has gone through a 42-year history. In the 42 years of vicissitudes, the copper ore grade fell from 1.175% to about 0.25%, and the by-product iron ore grade dropped from 30% to 16 to 17%. The annual processing volume of ore decreased from 1.4 million tons to 750,000 tons, and the output of copper metal decreased from the maximum of 3,000 tons/year to 1225 tons/year. By-product iron ore concentrates from 250,000 tons/year
