Talking toxic tailings reprocessing in Zambia
Part of Central Africa's copperbelt, the city of Kabwe in Zambia has been described by some as "the world's most toxic town". For almost a century it was home to a poorly regulated lead mining and smelting industry before the main state-controlled mine closed in 1994, leaving behind millions of tons of tailings and pollution that has since …Web
