The collapse in numbers: How South Africa lost its ferrochrome dominance.
The resource paradox at the heart of South Africa’s industrial decline.
According to a Discovery Alert report by Muflih Hidayat on 26 May 2026 few contradictions in global commodity markets are as striking as South Africa’s position in the chrome industry. The country sits atop an estimated 80% of the world’s economically viable chrome ore reserves, the foundational raw material for stainless steel production worldwide. Yet despite this extraordinary geological endowment, South Africa processes only a fraction of what it mines into finished ferrochrome. The value addition, the employment, and the export revenue that should logically flow from this resource dominance have, over the past two decades, migrated almost entirely to China.
This is not a story about depleted orebodies, logistical failure, or a lack of technical expertise. It is, at its core, a story about electricity pricing. And right now, a single proposed tariff rate – the Eskom ferrochrome smelter tariff 62c/kWh – is determining whether South Africa’s remaining ferrochrome smelting capacity survives or follows its predecessors into permanent closure.
The scale of the market share erosion that has taken place over the past 25 years is difficult to overstate. In 2001, South Africa accounted for roughly 51% of global ferrochrome output. Today, that figure has contracted to approximately 10%. Over the same period, China’s share expanded from around 5% to 65% of global production, despite China possessing negligible domestic chrome ore reserves of its own.

The mechanism driving this transfer is straightforward: Chinese smelters import chrome ore from South Africa and process it domestically using electricity priced far more favourably for industrial users than anything available to South African producers. The finished ferrochrome is then sold into global stainless steel supply chains at a cost structure South African smelters simply cannot match at prevailing Eskom tariff rates. Furthermore, ferroalloys in South Africa have long been considered critical to the country’s industrial identity, making this decline all the more consequential.
A critical and often underappreciated detail within these figures is that much of the capacity shut down over this period is now considered permanently unrecoverable. Submerged arc furnaces that have been idle for extended periods cannot simply be restarted. Infrastructure deteriorates, skilled workforces disperse, and the capital required to recommission mothballed smelters frequently exceeds the economics of doing so.
Consequently, the industry’s realistic production ceiling has been permanently compressed, even if tariff conditions were to improve dramatically overnight. Compounding this structural damage, Eskom’s tariffs to ferrochrome smelters have increased by more than 500% since 2010. The standard industrial tariff currently exceeds 200 cents per kilowatt-hour, a rate at which South African smelter operations are commercially unviable.
The original negotiated pricing agreements held by Samancor Chrome and the Glencore-Merafe Chrome Venture were already significantly discounted at 136c/kWh, yet even this preferential rate proved insufficient to maintain competitiveness as ferrochrome prices softened and operational pressures intensified. Indeed, South Africa’s mining decline has accelerated across multiple commodity sectors under similar pressures.
Why electricity is unlike any other production input
Understanding why the Eskom ferrochrome smelter tariff 62c/kWh debate matters so profoundly requires appreciating a technical reality specific to the smelting process. Electricity is not simply one cost among many in ferrochrome production. It constitutes approximately 52% of total production costs, making it the single largest operational variable by a wide margin.
Unlike labour costs, which can be partially managed through productivity improvements, or raw material costs, which track underlying commodity markets, electricity pricing in South Africa is a policy-controlled variable. This means the government and its regulatory architecture have both caused the problem and hold the primary lever to address it. The 62c/kWh proposal is, in essence, an attempt to use that lever before the remaining operating capacity crosses the threshold of no return.
Ferrochrome is produced by smelting chromite ore with a reductant, typically coke or coal, in submerged arc furnaces operating at extremely high temperatures. These furnaces run continuously and consume enormous quantities of electricity. There is no energy-efficient alternative process commercially available at scale.
This technological constraint means that ferrochrome producers cannot simply invest their way out of a high electricity price environment the way a manufacturer might through automation or process redesign. The fundamental physics of smelting sets a floor on energy consumption. Moreover, commodity prices and mining performance are inextricably linked, and when input costs spiral, entire value chains become uncompetitive.
The Eskom 62c/kWh tariff: Structure, terms, and revenue protection
The proposed revised negotiated pricing agreement represents a further step down from the 87.74c/kWh interim hardship tariff that Nersa approved in January 2026 after Samancor Chrome and the Glencore-Merafe Chrome Venture invoked distress provisions within their existing contracts. That interim arrangement was itself already a concession from the 136c/kWh rate embedded in their original NPAs.
The proposed 62c/kWh structure differs importantly from a conventional tariff reduction. It is a commercially engineered agreement containing multiple mechanisms designed to protect Eskom’s financial position.
