The IEA’s 2026 minerals outlook identifies disrupted sulphur supplies and higher sulphuric-acid costs as a consequence of the Middle East conflict. It says about half of seaborne sulphur trade passes through Hormuz and notes China’s May 2026 acid-export curbs. That describes the report period; it does not establish October shipping conditions.
Ivanhoe Mines ($IVN) offers a useful example. In its 13 April Q1 production release, it reported 117,871 tonnes of high-strength sulphuric acid produced by Kamoa-Kakula’s smelter during the quarter. The release also warned of reagent shortages affecting oxide-copper processing. These are the company’s reported figures and assessment, not an independently verified October run rate.
Our view: the inputs deserve as much attention as the ore. The ore can be there. The plant can be built. The missing reagent still gets the final vote.
The question hiding behind the copper price
A model that follows copper prices, grades and electricity costs can still miss the consumable that makes the process work. Before debating the next great supply deficit, ask what this particular plant needs to run, where it comes from and how long the stock on site will last.
The word particular does some work here. We would not give every copper, nickel or lithium operation the same acid sensitivity. Read the flowsheet. A neighbouring mine can use different chemistry and face a different problem.
A tank of acid is not yet a windfall
A persistent shortage could squeeze an acid buyer and help a producer with saleable surplus. Ivanhoe’s disclosure makes that second possibility worth examining. It does not establish surplus volumes, realised prices, customer access or future profit.
Before pencilling in a by-product windfall, ask how much acid the operation uses itself. Then check specification, contracts and delivery costs. The tank may be full. The revenue line still needs a customer.
For the buyer, ask about storage, alternative suppliers, delivery times and flexibility in the blend or process. These are reasonable questions at a results call. Waiting for a production downgrade makes them rather more expensive questions.
What would spoil this thesis?
Normalising trade, replacement supply or weaker demand could loosen the market. A short-lived price spike would be a poor foundation for valuing acid revenue over the life of a mine.
An integrated smelter also needs scrutiny on its own terms. An acid credit could help one part of the economics while commissioning problems, maintenance or other costs hurt another. Add the whole bill before admiring one line of it.
The Take: follow the reagents as closely as the rock. An acid buyer and an acid producer can have very different exposure to the same disruption. The interesting question is whether the economics survive the full operating bill.
