东京2020奥运会的金、银、铜牌正式向世人亮相，但是制作奖牌的原料你了解从哪来？

日前，东京奥组委发布了2020东京奥运会奖牌制作过程的短片。据东京奥组委介绍说，日本从2017年4月1日开始用两年的时间在日本全国收集了约7万8985吨的小家电和621万部旧手机，从中提炼出32公斤的纯金、3500公斤纯银和2200公斤纯铜，所有的奖牌均来自这些回收提炼的金属。

从奖牌规格上讲，金、银、铜牌的直径均宽85毫米，净重分别为556克、550克、450克。其中，金牌和银牌的重量创下历届夏季奥运会奖牌重量之最。

在短片中，详细展示了制作奥运会奖牌的全过程，包括回收的废旧电子设备(基本全部是翻盖手机)，拆下主板回收熔炼，设计奖牌模具，奖牌压制成型，清洗打磨，激光刻字，编制奖牌带，制作原木奖牌盒，机械之美与日本职人手作贯穿全程，让人心旷神怡。
