The development of the aluminum-copper industry has given way to precision management in China without the extensive mode of production. In the external world, it has exerted its power in both directions of resource acquisition and capacity integration. According to insiders of Chinalco, last year China Copper completed the integration of the domestic assets of the copper plate. Projects such as Prang Copper Mine, Tongchanggou Copper and Molybdenum Mine, and Qinghai Niu Bitou Lead-Zinc Mine, which are key projects, have been put into trial operation. Southeast, north of the three major copper smelting base has been completed. Among them, the Pulang copper mine is extremely rich in mineral reserves and has been listed as one of the 47 key exploration projects in the whole country in the "12th Five-Year Plan" for non-ferrous metal industry. Chinalco insiders said in an interview with reporters: "After the completion of two major projects, namely, Southeast Copper Industry and Chifeng Cloud Copper in 2018, Chinalco's refined copper production capacity will double on a year-on-year basis and enter the domestic copper industry The first phalanx. "However, overseas, the Peruvian copper mine, as China's first-class large-scale ore mine in operation and construction in South America, has been transformed from a loss at the initial stage of production into a profit and its profitability is rapidly increasing.
