At 20:06 local time in Zambia on June 7, 2025, the site of the oxygen-free copper rod project of JCC (Zambia) Optoelectronics Co., Ltd. (hereinafter referred to as "JCC Zambia") was filled with jubilation—the up-casting furnace was officially started for production. This key project, which carries the mission of optimizing the industrial layout of JCC South China Company in Zambia, achieved a crucial breakthrough, adding another footnote to the in-depth development of the Belt and Road Initiative on the African continent. After 270 days of intense efforts, the oxygen-free copper rod production line with a designed capacity of 8,000 mt per year was finally successfully started for production, marking the official commissioning of the largest and most advanced copper processing benchmark project in Zambia to date.
