A growing gap between local prices and what international buyers are offering has become a mounting concern among South African chrome ore traders, with industry participants warning that the market is being skewed by pricing benchmarks that do not reflect the true cost structures of reliable, large-scale operations. Several traders have told SMM that international buyers are increasingly anchoring their offers to prices set by smaller traders operating low-cost wash plants. These smaller operations have significantly lower overheads and can afford to sell at levels that bear little resemblance to the actual production and logistics costs borne by larger, more established producers. Traders stress that international buyers are treating these low-end prices as market benchmarks without distinguishing between the vastly different value propositions offered by small-scale suppliers versus major operations backed by large, secure mines. Traders representing partnerships with big South African chrome ore mines point to key value-adds that justify a premium over low-cost wash-plant supply — value-adds they feel are being systematically overlooked. These include stronger quality assurances, greater resilience in supply continuity during adverse conditions, and the ability to sign firm contracts guaranteeing fixed volumes on consistent, agreed schedules such as weekly deliveries. Moisture content, a recurring buyer concern, was highlighted as an area where established operators can offer greater control and reliability — a point given added relevance by the severe winter weather that has recently hit South Africa, with a cold front and cut-off low pressure system bringing heavy snow, disruptive rain, strong winds and freezing temperatures across parts of the country. The broader concern among South African traders is that international buyers are not adequately factoring operations costs, operational stability, supply certainty, and quality assurance into their pricing decisions. With the gap between low-cost, smaller-scale supply and premium, large-scale production widening, traders are calling for greater market awareness of the cost realities and service levels that differentiate reliable, long-term partners from spot-market players offering bargain prices without the same commitments.

SMM August 12: A sudden supply-side disruption has significantly altered the short-term supply-demand balance in the alumina market outside China. On August 11, Hydro’s Alunorte alumina refinery in Brazil was forced to activate emergency response measures due to a natural gas supply outage, cutting alumina production to 50% of capacity. The refinery has an existing capacity of 6.3 million mt/year, and after the 50% cut, the operating capacity fell to around 3.15 million mt/year, equivalent to a monthly production loss of approximately 250,000 mt—a non-negligible impact on the overall supply landscape outside China. Before this unexpected production cut, the alumina market outside China was in a slight surplus: in July, global alumina supply (excluding China) exceeded demand by about 486,000 mt, reflecting a loose supply-demand pattern. However, with Alunorte’s sharp output reduction, the August overseas surplus is expected to narrow quickly to around 177,000 mt. It is worth further noting that alumina prices outside China still lag behind domestic levels. This price spread means some alumina needs to be transshipped and repackaged in China before it can be exported, adding extra packaging and logistics costs. At the same time, China still maintains a net-import pattern for alumina, with monthly net imports averaging around 100,000 mt. Taken together, the actual surplus available for supply outside China will be further squeezed to merely about 70,000 mt. The supply-demand balance will abruptly shift from relatively loose to a tight balance, significantly elevating the risk of regional structural shortages, and alumina prices outside China are highly likely to find upward support in the short term. However, it must be objectively recognized that the price rally is not solely driven by Alunorte’s production cuts. Another structural support factor exists in overseas markets: due to strait passage issues, demand for bagged alumina in the Middle East is relatively urgent, while bulk alumina cannot effectively meet local supply because of transportation constraints. This situation has prompted some traders to first sell bulk alumina and then turn to purchase bagged alumina to fill the gap. Bagged alumina itself commands a notable premium—its FOB price is typically more than $20/mt higher than that of bulk alumina. This extra packaging and logistics cost has, to some extent, pushed up the overall price center in the regional market, serving as a secondary support for near-term alumina price strength outside China. Even if short-term sentiment and supply-demand fundamentals converge to drive prices higher, the upside room for alumina prices outside China may remain relatively limited. The core reason is that India still has plans to launch new capacity—a 1 million mt/year alumina project is expected to gradually advance its expansion in Q4 this year and Q1 next year, which will effectively supplement market supply at that time. Therefore, although supply was tight in Q3 due to production cuts at Alunorte, from a full-year perspective, the supply tightness in Q4 will ease noticeably, making it difficult to support a sustained sharp price increase. More attention should be paid to the uncertainty of disturbances on the time dimension. Currently, the duration of Alunorte’s natural gas supply issue remains unclear. If it is properly resolved in the short term, the impact of the production cuts will be relatively manageable; however, if the repair cycle is prolonged, the supply deficit outside China in Q3 will persist. Early signs of tight spot supply have already emerged in some regions. With the combination of fundamentals and sentiment, the likelihood of alumina prices outside China holding up well increases. Looking further ahead, new alumina capacity in Indonesia will be released gradually next year, and the global alumina supply landscape will evolve towards a looser balance, putting downward pressure on the long-term price center. In summary, the impact of this Alunorte production cut event on the alumina market outside China is mainly concentrated in Q3 this year. Short-term prices are expected to rise due to expectations of tightening supply-demand and regionally structural cost increases. However, constrained by the expectations of long-term growth from India’s new capacity about to be commissioned, as well as the continuous loosening pressure from capacity releases in Indonesia in Q4 this year and early next year, the current price rise reflects more of a periodic rebound rather than a trend reversal. It is expected that alumina prices outside China will consolidate on a strong note in Q3, and from Q4 to early next year, as new capacity comes online, the price center is likely to pull back gradually.

Lloyds Metals reported strong Q1 FY27 growth as iron ore production rose 53% y/y to 6.05 million tonnes, while the ramp-up of pellet and DRI capacity strengthened its shift toward integrated steelmaking and increased captive consumption of iron ore.

With this expansion, CMR expects its recycling capacity to exceed 700,000 tonnes per year by FY27.

Sentiment in China’s battery-grade manganese sulfate market has gradually returned to rationality, as the flood-related factors that previously lifted prices in Guangxi continue to ease.In early July, continuous heavy rainfall and floods hit major production areas in Guangxi. Rising river levels and disrupted logistics forced multiple manganese sulfate producers to suspend operations for safety inspections and equipment maintenance, triggering a temporary shrinkage of available spot supply.

[SMM Research] Nigeria remains a key supplier of tantalum concentrate, with exports largely priced on an FOB basis and driven by strong Chinese demand. Concentrate grades vary widely, with higher Ta₂O₅ content commanding significant premiums. Artisanal mining dominates supply, while informal trade continues to limit market transparency. SMM's research indicates that first-hand market intelligence remains essential for assessing pricing, quality and evolving supply chains.
