Sulphuric acid sits directly inside that equation. More oxide and mixed-ore processing means more acid consumption, more sulphur imports, more storage and more pressure to develop local production. **3.41Mt** DRC copper production in 2025 **+9.9%** 2025 copper production growth **6Mt** Approximate acid consumption cited for 2023 **7Mt+** Short-to-medium-term acid demand estimate The Democratic Republic of Congo has become one of the most important copper-producing jurisdictions in the world. That growth is creating a second market beside the metal itself: the industrial inputs required to keep hydrometallurgical plants running. Sulphuric acid is one of the most important of those inputs. It is used extensively in the leaching of copper-bearing oxide and mixed ores before solvent extraction and electrowinning, commonly known as SX-EW. According to the [DRC's Institut National de la Statistique ](https://www.ins.gouv.cd/statistiques/mines-petrole?metric=Cuivre&ref=blog.financely.io), national copper production reached approximately 3.41 million tonnes in 2025, compared with 3.10 million tonnes in 2024\. That represents annual growth of roughly 9.9%. ### The market in one sentence The DRC is building more copper capacity, processing enormous quantities of acid-consuming ore and adding local sulphuric acid production, but the scale of new acid supply still leaves a large market for sulphur, merchant acid, logistics, storage and dedicated mine supply contracts. ## Why copper production creates sulphuric acid demand The connection comes from hydrometallurgy. Many Copperbelt operations recover copper from oxide material by crushing the ore and exposing the copper minerals to sulphuric acid. The resulting copper-bearing solution moves through solvent extraction before copper is recovered through electrowinning. This makes sulphuric acid an operating input rather than a peripheral consumable. A mine with insufficient acid can have ore in the ground, processing infrastructure and available power while still struggling to maintain planned cathode production. Acid consumption also changes with mineralogy. Different ores require different acid dosages. As mines progress through deposits and encounter mixed ores, altered material or more difficult mineralogy, reagent requirements can rise even when copper output remains relatively stable. ### More copper tonnes Higher SX-EW throughput generally creates greater demand for sulphuric acid, assuming the production mix continues to include oxide and acid-leachable material. ### Changing ore characteristics Acid demand depends on the chemistry of the ore. Lower grades and changing mineralogy can increase reagent consumption per tonne of recovered copper. ### New processing capacity Expansion of leach circuits, SX-EW plants and copper-cobalt processing facilities creates additional long-term reagent demand. ### Growing cobalt production The wider copper-cobalt hydrometallurgical chain requires substantial chemical inputs, strengthening demand for reliable industrial chemical supply across Lualaba and Haut-Katanga. ## The DRC could require more than 7 million tonnes of acid The size of the market explains why new domestic production is being absorbed quickly rather than automatically creating a structural surplus. Ivanhoe Mines has previously estimated that DRC mining operations consumed approximately **6 million tonnes of sulphuric acid in 2023**. The company projected domestic demand to rise above **7 million tonnes in the short to medium term**. The estimate was published as Ivanhoe developed the direct-to-blister smelter at Kamoa-Kakula. The facility captures sulphur dioxide generated during smelting and converts it into high-strength sulphuric acid. This creates an interesting feature of the Copperbelt market. Sulphide copper processing can produce acid, while nearby oxide copper operations consume it. Smelting and hydrometallurgical production can therefore become commercially linked through local acid offtake. Ivanhoe's [published market estimates ](https://www.ivanhoemines.com/news-stories/news-release/ivanhoe-mines-issues-second-quarter-2024-financial-results-and-review-of-construction-and-exploration-activities/?ref=blog.financely.io)provide an indication of just how large that local requirement has become. ## Kamoa-Kakula is changing the local acid supply picture The Kamoa-Kakula smelter is one of the most important additions to the DRC's sulphuric acid supply base. During the second quarter of 2026, Ivanhoe reported that the smelter was producing approximately **1,250 tonnes of high-strength sulphuric acid per day**. That is equivalent to roughly **450,000 tonnes per year** on an annualized basis. The plant has a steady-state design capacity of up to **700,000 tonnes per year**. The acid is sold to nearby mining operations in the DRC Copperbelt rather than transported to distant export markets. Ivanhoe also reported that its expected realized acid price for July 2026 was approximately **US$840 per tonne**. Earlier in the year, the company had six mine-gate offtakers purchasing acid from Kamoa-Kakula. **Why this matters:** even 700,000 tonnes of annual production would represent only a fraction of a DRC market estimated in the millions of tonnes. Kamoa-Kakula adds meaningful local supply, but it does not remove the underlying requirement for additional acid and sulphur. The latest operating figures are available in [Ivanhoe Mines' Q2 2026 production update ](https://www.ivanhoemines.com/news-stories/news-release/ivanhoe-mines-reports-64328-tonnes-of-copper-produced-by-kamoa-kakula-in-q2-2026/?ref=blog.financely.io). ## CMOC's expansion provides another demand signal CMOC's Tenke Fungurume Mining and Kisanfu operations are another useful indicator of the scale being reached in the Congolese copper-cobalt industry. CMOC reports that its DRC operations produced approximately **741,100 tonnes of copper**and **117,500 tonnes of cobalt** in 2025\. TFM now has annual copper capacity above 450,000 tonnes while KFM has capacity above 200,000 tonnes. The company is also advancing KFM Phase II. The project is expected to enter production in 2027 and add another **100,000 tonnes of annual copper capacity**. Significantly for the acid market, CMOC has also disclosed plans for construction of a **200,000-tonne-per-year sulphuric acid plant** alongside the KFM expansion. The investment shows how major producers increasingly view secure acid supply as part of mine infrastructure rather than something that can always be left to the spot market. Details of the DRC operations and KFM expansion are available from [CMOC Group ](https://en.cmoc.com/html/Business/Congo-Cu-Co/?ref=blog.financely.io). ## Local acid production still competes with imported sulphur The DRC's sulphuric acid market cannot be understood purely by looking at direct acid imports. A substantial share of the country's supply chain begins with elemental sulphur. Sulphur can be transported into the Copperbelt and burned in sulphur-burning acid plants close to the consuming mines. This is often more practical than moving very large quantities of finished sulphuric acid over long international logistics corridors. The result is effectively two connected markets: - finished high-strength sulphuric acid supplied by smelters and merchant producers; and - elemental sulphur imported as feedstock for local acid production. Both supply chains are exposed to transport capacity, port congestion, border movements, storage, fuel costs and international sulphur availability. ## 2026 showed how quickly the market can tighten The vulnerability became particularly visible during 2026 as international disruptions affected chemical and sulphur shipments into the region. Reuters reported that DRC sulphur imports fell from roughly 414,600 tonnes in the first quarter of 2025 to approximately 368,500 tonnes during the same period in 2026\. Direct sulphuric acid imports dropped from approximately 113,000 tonnes to around 29,200 tonnes. At the same time, regional acid flows were affected by restrictions on exports from neighbouring Zambia. These disruptions pushed miners toward available domestic production and helped support unusually high mine-gate pricing. | Market factor | Impact on DRC acid demand or supply | | ----------------------------- | ------------------------------------------------------------------------------- | | Rising copper production | Increases reagent requirements at oxide and mixed-ore processing operations. | | KFM and other mine expansions | Adds future processing capacity and long-term chemical demand. | | Kamoa-Kakula smelter | Adds up to 700,000 tpa of local high-strength sulphuric acid supply. | | Imported sulphur dependence | Exposes domestic acid production to international logistics and sulphur prices. | | Zambian export restrictions | Reduces an important source of regional merchant acid during tight periods. | | Long inland logistics | Raises delivered cost and increases the value of reliable local supply. | ## The commercial opportunity is wider than selling acid Demand growth creates opportunities across the entire supply chain rather than only in physical sulphuric acid trading. ### Long-term acid offtake Mines can contract with smelters and acid producers for committed volumes instead of relying entirely on short-term purchases. ### Sulphur imports Traders can supply elemental sulphur to mine-owned and third-party sulphur-burning plants under annual or multi-shipment contracts. ### Storage infrastructure Tank capacity and properly designed chemical handling infrastructure can provide buffer inventory against transport and border disruptions. ### Acid plant development Dedicated sulphur-burning plants can be developed around large anchor offtakers where contracted demand supports the capital expenditure. ### Trade finance Importers may require letters of credit, inventory facilities, supplier finance or borrowing-base structures to fund sulphur and acid moving through the supply chain. ### Prepayment structures Contracted mine demand can support prepayment or structured working-capital facilities where lenders have sufficient control over inventory, cash flows and offtake. ## Financing will matter as volumes rise A large physical chemical contract consumes working capital quickly. Suppliers may have to purchase sulphur internationally, pay freight, fund inventory in transit, carry material at inland depots and extend payment terms to the mine. The financing requirement can therefore become significant well before the supplier receives cash from the final buyer. Transactions with established mining counterparties can potentially be structured around purchase contracts, confirmed orders, letters of credit, receivables, controlled inventory or contracted offtake. Larger infrastructure projects may require separate project or asset-backed financing for acid plants, storage terminals and associated logistics equipment. Credit analysis still has to address the full transaction. This includes the mine counterparty, supplier performance, import permits, dangerous-goods handling, insurance, storage, transport, pricing mechanisms and the ability to redirect product if the primary buyer fails to perform. ## The DRC acid market is becoming part of the copper investment thesis Copper production receives the headlines. Reagents, power, transport and processing capacity determine how much of that copper can actually be produced. The DRC produced around 1.6 million tonnes of copper in 2020\. By 2025, production had climbed above 3.4 million tonnes. That growth changes the scale of the industrial ecosystem surrounding the mines. Sulphuric acid is one of the clearest examples. Domestic acid production is expanding. Kamoa-Kakula is adding hundreds of thousands of tonnes. CMOC is building additional capacity. Other smelters and sulphur-burning plants already form part of the regional supply base. Yet demand is measured in millions of tonnes and additional copper capacity continues to enter the pipeline. For commodity traders, chemical suppliers, logistics companies, lenders and infrastructure investors, sulphuric acid should therefore be viewed as a distinct Copperbelt market in its own right rather than simply a minor consumable attached to copper mining. ### What to watch next The most important indicators are Kamoa-Kakula's acid ramp-up, KFM Phase II, new sulphur-burning capacity, regional sulphur availability, Zambian export policy, mine expansion schedules and delivered acid prices around Kolwezi and the wider Copperbelt. ## Financing a Copperbelt commodity or mining supply transaction?
