Las Medulas, Spain, was the largest gold mine in Roman times.
This from Las Médulas - Wikipedia
“The massive scale of mining at Las Médulas and other Roman sites had considerable environmental impact. Ice core data taken from Greenland suggest that mineral air pollution peaked during the Roman period in Spain. Levels of atmospheric lead from this period were not reached again until the Industrial Revolution some 1,700 years later.“
