Copper Boom Widens Profit Gap Between Chinese Miners and Smelters
Rising copper prices are strengthening profits for low-cost mining companies while placing increasing pressure on smelters. The World Bank forecasts copper averaging $13,000 per metric ton in 2027, but declining processing charges mean the benefits of the rally are unevenly distributed.
Key Points
- Copper outlook: World Bank forecasts an average price of $13,000/MT in 2027, 18% above its April estimate.
- Mining margins: Zijin Mining's reported copper concentrate gross margin increased from 65% to 71%.
- Smelting pressure: The 2026 annual benchmark treatment charge fell to $0/MT, with spot charges remaining negative.
- China's position: The country accounts for more than half of global copper smelting and refining capacity.
- Investment outlook: Low-cost mining operations are better positioned to capture the benefits of stronger copper prices.
SEATTLE (Scrap Monster): The global copper rally is creating sharply different outcomes for mining companies and smelters, according to an analysis published by the Financial Times.
Demand expectations linked to electricity infrastructure, artificial intelligence and the energy transition are supporting copper prices. The World Bank now expects copper to average $13,000 per metric ton in 2027, an increase of approximately 18% from its previous forecast.
However, stronger copper prices are not translating into equally strong earnings throughout the production chain.
ScrapMonster Edge: Copper's Rally Rewards Mining More Than Processing
Mining and smelting businesses face different economics. Low-cost miners benefit when copper selling prices rise faster than extraction costs. Smelters, meanwhile, depend partly on treatment and refining charges earned from processing copper concentrate.
China's rapid expansion of smelting capacity has increased competition for available concentrate, pushing processing charges to historic lows despite elevated refined copper prices.
Smelters may offset some of that pressure through by-product sales and other commercial arrangements, but the headline copper price alone does not reveal their profitability.
Industry takeaway: For copper recyclers, processors and industrial buyers, higher copper prices should not be interpreted as evidence of stronger margins across every part of the industry. Mine production costs, concentrate availability, processing charges and recovered-metal economics must be assessed separately.
Zijin Mining Benefits From Lower Production Costs
Chinese mining group Zijin Mining illustrates the advantages available to producers operating relatively low on the global copper cost curve.
According to the Financial Times analysis, Zijin's copper concentrate gross margin increased from approximately 65% in the first quarter of 2025 to 71% one year later.
The improvement reflects rising realized copper prices relative to the company's unit production costs.
Zijin's operating cash flow also nearly doubled during the first half of 2026, strengthening its ability to fund new projects and pursue mining acquisitions.
China's Smelters Face Negative Processing Charges
Conditions are considerably more difficult for smelters purchasing copper concentrate.
China has expanded processing capacity faster than global concentrate supplies have grown, intensifying competition among smelters for feedstock.
The annual benchmark copper treatment charge reached $0 per metric ton in 2026, compared with $21.25/MT in 2025. Spot treatment charges have fallen below zero.
The International Energy Agency has identified both constrained concentrate availability and China's rapid smelter expansion as major contributors to the decline.
Smelters increasingly depend on revenues from recoverable by-products and negotiated contract terms to support processing margins.
Copper Supply Growth Creates Different Investment Opportunities
China remains central to global copper production and processing. Its mining companies have expanded overseas, while the country continues to dominate global smelting and refining capacity.
The Financial Times noted that Zijin Mining shares traded at just under eight times forward earnings, a discount to several international mining companies despite its scale and resource base.
The valuation comparison highlights how investors may assess geographical exposure, company structure and other risks differently across copper producers.
For the broader copper industry, the central issue is how much of the value created by elevated prices is retained by miners, smelters and other processors.
With copper demand expected to benefit from electrification and data-centre development, that distinction will remain important as companies evaluate capacity expansions, operating costs and future investment.
