Guinea's bauxite mining development | CRU
CRU segments the bauxite market into integrated and third-party markets. Third-party bauxite demand occurs when a refinery purchases either a proportion or its entire bauxite requirements from a mine that is not owned by the refinery. That is, the refinery is not associated with the bauxite mine, and thus the buyer and seller are non-related ...
