[00:00:00]Why is Switzerland's gold considered the purest in the world? Look, [music] gold is mined from all over the world, but it's not turned directly into perfect gold bars. These gold bars [music] are not 100% pure because they contain silver, copper, and other metals. That's why they're sent to Switzerland for refining. [music] There, the bars are melted at around 1,000° C.

[00:00:18]Then, chlorine gas is added to separate silver, copper, lead, and other impurities. At this point, the gold becomes about 99.5% pure. But, Swiss refiners don't stop there. They use gold electrolysis to remove even microscopic dirty one by one. And only then does the gold reach up to 99.999% purity.
