Is mercury worth more than gold?

The gold:mercury price ratio is an indicator of the relative cost of using mercury to extract gold. Overall, the price increase makes mercury more expensive for uses, legal or illegal, and will, to some degree, be an incentive for increased conservation and recycling or switching to non-mercury alternatives.

How do you convert mercury into gold?

Using fast neutrons, the mercury isotope 198Hg, which composes 9.97% of natural mercury, can be converted by splitting off a neutron and becoming 197Hg, which then decays into stable gold.
