The Congo’s role in creating the bombs dropped on Hiroshima and Nagasaki was kept secret for decades, but the legacy of its involvement is still being felt today.

“The word Shinkolobwe fills me with grief and sorrow,” says Susan Williams, a historian at the UK Institute of Commonwealth Studies. “It’s not a happy word, it’s one I associate with terrible grief and suffering.”

Few people know what, or even where, Shinkolobwe is. But this small mine in the southern province of Katanga, in the Democratic Republic of the Congo (DRC), played a part in one of the most violent and devastating events in history.

...
The story of Shinkolobwe began when a rich seam of uranium was discovered there in 1915, while the Congo was under colonial rule by Belgium. There was little demand for uranium back then: its mineral form is known as pitchblende, from a German phrase describing it as a worthless rock. Instead, the land was mined by the Belgian company Union Minière for its traces of radium, a valuable element that had been recently isolated by Marie and Pierre Curie.

It was only when nuclear fission was discovered in 1938 that the potential of uranium became apparent. After hearing about the discovery, Albert Einstein immediately wrote to US president Franklin D Roosevelt, advising him that the element could be used to generate a colossal amount of energy – even to construct powerful bombs. In 1942, US military strategists decided to buy as much uranium as they could to pursue what became known as the Manhattan Project. And while mines existed in Colorado and Canada, nowhere in the world had as much uranium as the Congo.

“The geology of Shinkolobwe is described as a freak of nature,” says Tom Zoellner, who visited Shinkolobwe in the course of writing Uranium – War, Energy, and the Rock that Shaped the World. “In no other mine could you see a purer concentration of uranium. Nothing like it has ever been found.”

Mines in the US and Canada were considered a “good” prospect if they could yield ore with 0.03% uranium. At Shinkolobwe, ores typically yielded 65% uranium. The waste pile of rock deemed too poor quality to bother processing, known as tailings, contained 20% uranium.
