A fascinating theory proposes the Baghdad Battery extracted precious metals from mine runoff. Gold, silver, and copper accumulate on the cathode through electrochemical reduction. This electrowinning process explains the missing residue - metals were harvested. To ancient observers, this looked like alchemy.
Key facts claimed:
- Baghdad Battery artifacts consist of iron and copper metals submerged in electrolytic solution
- Objects function as galvanic cells using oxidation-reduction processes to generate electron flow
- Iron designated as anode (negative pole) and copper as cathode (positive pole)
- Artifacts discovered near Khujut Rabu archaeological site (30+ km southeast of Baghdad)
- Consists of a ceramic jar containing a copper cylinder with a vertical iron rod inside
