The Geological Characteristics, Resource Potential, and Development Status of Manganese Deposits in Africa

Manganese is a critical metal extensively used in steel production, battery manufacturing, and the chemical industry. Manganese deposits are widely distributed globally, with African manganese deposits holding a particularly significant position. This study provides a comprehensive overview of the current status of manganese resources in Africa and analyzes the main types and genesis of the deposits. It also explores the significance of African manganese resources within the global manganese industry and examines the exploration, development, production, and trade status of African manganese ore, revealing dynamic changes and trends within the industry. Africa plays a key role in global manganese resources, with its reserves and resources accounting for 69% and 51% of the global totals, respectively. South Africa is the largest manganese producer, while Gabon and Ghana are also important countries in terms of manganese resources. Based on the host rock and genetic types, African manganese deposits primarily include banded iron formation (BIF)-hosted, black shale-hosted, karst-hosted, and volcanic sedimentary deposits. Additionally, manganese exploration projects in Africa are active, with significant production growth in South Africa and Gabon, and Africa’s standing in the global manganese market is steadily increasing. Trade data also indicate that South Africa dominates manganese exports in Africa and globally. Despite fluctuations in global export volumes, African manganese exports remain high. The prospects for Africa’s manganese industry are promising, and further strengthening of manganese exploration and development will help enhance Africa’s influence in the global manganese market, making a more significant contribution to global industrial and economic development.
