Africa's move from raw material exports toward mineral
Abstract For the last 500 years, the West has mapped Africa as a source of raw materials, disrupted vibrant African value addition, and arrogated itself as the place where industrial revolutions (value addition) happen. This strategy is clearly traceable from the transatlantic slave trade, continuing through European colonialism, to the current …
