Kabwe mine or Broken Hill mine is a retired lead smelting and mining operation near Kabwe, Zambia that operated from 1906 to 1994. At its peak, between 1925 and 1974, it was Africa's largest lead producer. The mine produced extremely toxic lead pollution for ninety years and poisoned over 100,000 people including tens of thousands of children. Some pollution experts have said that Kabwe may be the world's most polluted town.
