the 1830s Chile produced nearly a fifth of the world output of copper
while Cornwall provided more than half. But a decade later Chile had
surpassed Cornwall, and by the 1850s when Cornish mines produced barely
a quarter of the world’s copper supply, Chile was providing over 40
per cent. This map depicts the main Chilean metalliferous mining
that enabled Chile to dominate global copper ore production in the mid
to late nineteenth century.
