（文华综合 ） 国家统计局发布报告显示，中国12月精炼铜（电解铜）产量为132.6万吨，同比增加9.1%。1-12月累计 产量为1,472.0万吨，同比增长10.4%。虽然12月有部分冶炼厂检修，但实际影响产量有限，而前期检修 的冶炼厂陆续复产，另外，由于铜价持续拉升，使得精废价差大幅扩大，废产阳极铜的产量增加，冶炼 厂的原料得以有效补充，不少冶炼厂的产量均出现环比上升，12月铜产量环比增加。进入1月，SMM表 示，将有5家冶炼厂有检修计划，涉及粗炼产能105万吨，预计影响量约为1.9万吨。往年不少冶炼厂有 开门红的习惯，但今年由于铜精矿供应紧张，仅个别冶炼厂仍保持该习惯。另外，1月原计划是有2家冶 炼厂要投产，但因各种原因影响，仅一家能按时投产，另外一家要延后至3月底4月初。 ...

Group 1 - The core viewpoint of the article indicates that China's refined copper production in August 2025 reached 1.301 million tons, representing a year-on-year increase of 14.8% [1] - In August, only three smelters underwent maintenance, while two new smelters in East China continued to ramp up production, contributing to a slight month-on-month increase in refined copper output [1] - The high sulfuric acid prices in August helped offset smelting losses, and the processing fees for copper concentrate showed a trend of rising and then falling, which also supported the production levels [1] Group 2 - In September, five smelters are scheduled for maintenance, affecting a total of 1 million tons of crude smelting capacity, leading to an expected production decrease of 14,000 tons compared to August [1] - Apart from routine maintenance, a significant reduction in production is anticipated due to tight supply of anode copper, which is expected to impact 60% of the surveyed sample, resulting in a substantial decline in September output [1]
