Guinea's bauxite mining development

2020/8/20China's drive for increasing alumina production presented a new opportunity for Guinea to accelerate the development of its vast mineral endowment. With China's own bauxite supply declining in quality, and resource nationalism in countries such as Indonesia and Malaysia preventing more obvious sources, the matter became of key interest for China – and an opportunity for Guinea.
