全球铁矿石市场格局迎历史性重塑：非洲成关键角色

Over the past half-century of industrialisation, the global seaborne iron ore market consolidated around a duopoly dominated by Australia's Pilbara region and Brazil's Carajás and Iron Quadrangle districts. However, driven by macroeconomic cycle evolution, a structural shift in China's growth engine, and the steel industry's irreversible push toward low-carbon and green transformation, this traditional supply map is undergoing an unprecedented reshaping.

On 26 November 2025, the first commercial vessel loaded with Simandou iron ore departed from the Port of Mabarya, marking the official commissioning of Guinea's Simandou Iron Ore Project — the world's largest undeveloped high-grade greenfield iron ore deposit by reserve. This milestone signals that the African continent, long relegated to secondary status, is progressively emerging as a significant new force in the global ferrous metals market.

Africa's iron ore resources are widely regarded as the third-largest iron ore supply region globally, after Brazil's Carajás and Australia's Pilbara. With an estimated 13.8% share of global iron ore resources, and representing the most significant supply-side growth driver over the next five years, shifts in African iron ore dynamics will be a key determinant of international iron ore pricing over the long term.

I. Global Iron Ore Market Background

According to SMM research data, global iron ore production in 2025 is estimated at approximately 2.472 billion tonnes (bt). Africa contributes roughly 95 million tonnes (Mt), representing close to 4% of global output. As major mining projects progressively come on stream, Africa's iron ore production capacity is forecast to double by 2030, reaching approximately 259 Mt. Assuming no production curtailments elsewhere, Africa's global market share could rise to nearly 10%, while the overall global iron ore supply surplus is projected to widen to approximately 220 Mt.

Although the international iron ore market has already entered a prolonged loose supply cycle, the substantive supply shock from African iron ore is expected to materialise gradually over the next five years. In the near term, Africa's estimated incremental shipment of approximately 15 Mt in 2026 — bolstered by its superior high-grade characteristics — is expected to be absorbed relatively smoothly by steelmakers seeking low-carbon blending feedstocks, resulting in a relatively moderate impact on absolute benchmark pricing.

The critical inflection point is projected to fall in 2028–2029. As rail and port infrastructure currently under construction in West Africa is fully commissioned, a surge in high-grade iron ore output will exert heavy downward pressure on the right-hand side of the global iron ore cost curve. This will not only systematically compress the iron ore price floor but will trigger intense structural displacement — squeezing the operating margin of low-grade, high-cost producers. The current price downcycle is expected to persist through 2028. When international ore prices breach the USD 90/tonne marginal cost support level, higher-cost non-mainstream small and mid-size mines will be forced into curtailment and exit. The resulting supply shakeout will reshape the global iron ore supply structure into a multi-oligopoly dominated by ultra-large, low-cost operations (including the new African mines), complemented by quality mid-tier producers.

II. Africa's Current Market Landscape: South Africa as Dominant Producer, West Africa Expanding Aggressively

Building on the global context, this section focuses on Africa's overall iron ore landscape. As the primary driver of supply growth over the next five years, Africa's iron ore production is concentrated in West Africa and South Africa, currently dominated by three key countries.

South Africa

South Africa is the continent's largest producer, with 2025 output reaching approximately 67 Mt and export shipments maintaining an overwhelming 65% share of total African iron ore exports. However, South Africa's iron ore sector faces structural constraints limiting its organic growth headroom. As other emerging African resource nations commission significant new projects, South Africa's share of total African export volumes is projected to face sustained compression.

Mauritania

Mauritania is Africa's second-largest iron ore producer, with 2025 output of 15 Mt and export volumes of approximately 12 Mt, representing approximately 12% of the African market. Strategically situated adjacent to the Atlantic Ocean with high-grade iron ore deposits deep within the Sahara Desert, Mauritania possesses highly advantageous geographic and mineralogical characteristics. Its proximity to European and Middle Eastern markets — both in urgent need of green industrial raw materials — provides ideal conditions for the country to become a hub for global green metallurgy capacity relocation. Mauritania is expected to emerge as a highly promising iron ore supply nation going forward.

Sierra Leone

Sierra Leone is another important regional supply pole, with projected 2025 output also reaching approximately 12 Mt, holding a stable share of approximately 12% in the African export market. Chinese-invested iron ore mines within the country are actively scaling up their operations.

Trade Flow Overview

Based on full-year 2024 trade data, the proportion of African iron ore shipped to China is relatively low compared to traditional mainstream ore origins, at approximately 60%. The broader Pan-Asian market — encompassing China, Japan, and South Korea — absorbs approximately 70% of total African iron ore shipments. Western European countries, led by the Netherlands and Germany, constitute Africa's core secondary destination, accounting for close to 14% of trade flows. The remaining marginal trade flows are broadly diversified, extending to emerging steelmaking capacity clusters in the Middle East, including Bahrain, Oman, and Saudi Arabia.

Key Corporate Players

At the corporate level, South Africa's Kumba Iron Ore and Assmang rank as Africa's largest and second-largest iron ore producers, with annual output of approximately 37 Mt and 17 Mt respectively.

Kumba Iron Ore: Kumba's mining operations — including the Sishen mine — are globally recognised for producing high-grade fines (Fe >62%) and metallurgically superior premium lump ore (Fe 65.2%). Under the prevailing trend of blast furnace (BF) emission reduction, this type of direct-charge lump ore — which reduces sintering-related carbon emissions — commands strong market demand and a substantial price premium.

Assmang: Assmang similarly holds high-quality iron ore assets, operated as a 50:50 joint venture between African Rainbow Minerals (ARM) and Assore. Its Assmang Fines and Assmang Lump products (Fe 64–65%) are also direct-charge, high-quality materials. However, the company's key bottleneck lies not at the pithead but on the rail. Heavy dependence on Transnet Freight Rail (TFR) for haulage means logistics constraints frequently cap its achievable shipment volumes.

SNIM (Société Nationale Industrielle et Minière): Mauritania's state-owned mining company is Africa's third-largest iron ore producer after the two South African majors. Unlike mainstream Australian and Brazilian ores, SNIM products occupy a distinctive niche in terms of physicochemical specifications and market segment. Its most widely traded product, TZFC fines, is characterised by extremely low alumina (Al2O3) and phosphorus (P) content. As an excellent blending ore, major steelmakers regularly blend SNIM fines with high-alumina Australian fines (such as certain Pilbara blend products) to significantly dilute the impurity ratio in the burden, thereby optimising blast furnace performance metrics.
