As the key component in aluminum production, bauxite became one of the most important minerals of the last one hundred years. But its effects on people and economies varied broadly – for some it meant jobs, progress, or a political advantage over rival nations but for many others, it meant exploitation, pollution, or the destruction of a way of life. Aluminum Ore explores the often overlooked history of bauxite in the twentieth century, and in doing so examines the forces that shaped the time, from the mineral’s strategic development in the First World War and throughout the Cold War, to its role in the globalization of markets, as companies from the northern hemisphere vied for the resources of the south. In this wide-ranging collection, scholars from around the world consider multiple international perspectives on this history – from Guinea to Nazi Germany to Jamaica – all while examining the central place of one commodity in a time of change.
