I want to know the answer to the following question:
During the 6th through 3rd centuries BC how much copper was mined in Rome?
All the background I'm provided with is that "With an estimated annual output of around 15,000 t, Roman copper mining and smelting activities reached a scale unsurpassed until the time of the Industrial Revolution; the provinces most intensely mined were those of Hispania, Cyprus and in Central Europe.". Is that enough to answer the question?
