Gabon Manganese Export Ban Takes Effect in 2029

Gabon Manganese Mining

Gabon announced a complete Gabon manganese export ban on unrefined ore starting January 2029. The world's second-largest manganese producer aims to boost domestic processing and industrial capacity. This transformative Gabon manganese export ban follows similar African resource nationalism strategies.

Major Impact on Global Manganese Supply Chains

Gabon produces 4.6 million tonnes annually, representing 25% of global manganese output. China and the US face significant supply disruptions from this policy change. Meanwhile, the US imported 63% of its manganese from Gabon last year. The ban threatens established supply chains for steel and battery industries worldwide.

French mining giant Eramet, through subsidiary Comilog, dominates Gabon's manganese sector. The company operates existing downstream facilities producing silico-manganese and manganese metal. However, current utilization remains low with only 18,000 tonnes exported in 2024. Comilog employs over 3,300 people locally, making workforce considerations critical.

African Resource Nationalism Accelerates

Several African nations now restrict raw material exports to capture value domestically. Guinea banned bauxite exports while Zimbabwe restricted lithium ore shipments recently. Furthermore, Mali and Tanzania implemented gold export restrictions this year. Therefore, the Gabon manganese export ban represents broader continental industrial ambitions.

President Brice Oligui Nguema emphasizes increased state revenues through downstream processing. Moreover, this strategy requires massive investment in new manganese alloy production capacity. As a result, international miners must develop processing plants or exit Gabon entirely. The five-year transition period allows stakeholders to adjust operations accordingly.

The Metalnomist Commentary

Gabon's 2029 manganese export ban creates immediate pressure on Western supply chains already strained by geopolitical tensions. With China controlling most manganese processing capacity globally, this move could paradoxically strengthen Beijing's market position unless Western nations rapidly develop alternative processing hubs. Eramet's underutilized facilities suggest the technical and economic challenges of African beneficiation remain substantial.
