青铜的出现和冶炼在生产力的发展上具有划时代的意义，在人类历史上有一个时期被称作“青铜时代”。铜的冶炼是化学史中的一件大事，因为这是人类第一次用化学方法从天然矿石中提炼的金属。本文探索内蒙古地区最早青铜器的出现和青铜的冶炼问题。考古资料表明，早在距今３１００多年前，内蒙古地区已有大型青铜器出现，并有可能是当地铸造的；到了战国时期（公元前４０３年～前２２１年），青铜器已大量使用，青铜冶铸业相当发达。 The emergence and smelting of bronze have epoch-making significance in the development of productive forces. In the history of mankind, there was a time called “the Bronze Age.” Copper smelting is a major event in the history of chemistry because it is the first time humans have chemically extracted metals from natural ores. This article explores the earliest bronzes in Inner Mongolia and the smelting of bronze. Archaeological data show that as early as in more than 3,100 years ago, there have been large bronze medal in Inner Mongolia, and may be locally cast; to the Warring States Period (403 BC ~ 221 BC), bronze has been extensive use of bronze smelting Industry is quite developed.
