统计局：前期检修复产&原料得到补充 12月中国铜产量大增

Group 1 - The core viewpoint of the article highlights that China's refined copper production in December reached 1.326 million tons, marking a year-on-year increase of 9.1% [1] - Cumulative production for the entire year of 2022 was 14.72 million tons, reflecting a year-on-year growth of 10.4% [1] - Despite some smelters undergoing maintenance in December, the overall impact on production was limited, with many smelters resuming operations and an increase in the production of scrap anode copper due to rising copper prices [1] Group 2 - In January, five smelters are scheduled for maintenance, affecting a total crude refining capacity of 1.05 million tons, with an estimated production impact of about 19,000 tons [1] - Traditionally, many smelters have a "New Year opening" practice, but this year, due to tight copper concentrate supply, only a few smelters are maintaining this practice [1] - Originally, two smelters were planned to commence production in January, but only one is expected to start on time, while the other has been delayed until late March or early April [1]
