Guinea, the world's largest producer of bauxite, is set to announce export control measures in June. This move aims to regulate the supply of bauxite, a key raw material in aluminum production, and potentially boost market prices. The decision comes as Guinea seeks to exert greater influence over the global bauxite market. The announcement is expected to impact global aluminum production, as Guinea's bauxite is a critical component in the supply chain. The country has been a dominant player in the bauxite industry, and these new measures could lead to shifts in market dynamics and pricing strategies for aluminum producers worldwide.
