Broken Hill Mine and Its Legacy of Pollution
The name Kabwe or Kabwe-Ka Mukuba means 'ore' or 'smelting' but the European/Australian prospectors named it after a similar mine in Broken Hill, New South Wales, Australia. The mine became the largest in the country until overtaken in the early 1930s by larger copper mining complexes on the Copperbelt. Apart from lead and zinc it also produced silver, manganese and heavy metals such as cadmium, vanadium, and titanium in smaller quantities.
In 1921 a human fossil (a skull) called Broken Hill Man or Rhodesian Man (classified as Homo rhodesiensis or Homo heidelbergensis) was found in the mine.
The mine, which occupies a 2.5 km² site just 1 km south-west of the town centre, is now closed but metals are still extracted from old tailings. A study by the Blacksmith Institute found Kabwe to be one of the ten worst polluted places in the world due mostly to heavy metal (mostly zinc and lead) tailings making their way into the local water supply.
