WebMercury battery uses HgO and MnO2. You can use redox potentials to easily isolate Hg(l). Find a metal more reactive than Hg but less than Mn. Make the battery a powder. Make the metal a powder, too. Mix them as intimately as possible and heat the mixture. You'll then get pure mercury. Id say zinc would be good, maybe iron.
