    Iran war squeeze on acid and aluminium: margin impacts for mine planners

    Iran war squeeze on acid and aluminium: margin impacts for mine planners

    First reported on MINING.com

    30 Second Briefing

    Iran’s war around the Strait of Hormuz has disrupted more than half of seaborne sulphur trade, shut in about 11 million barrels per day of crude and put 3–3.5 million tonnes of Middle East aluminium output at risk, driving sulphuric acid prices up 245% year-on-year and Europe’s duty-paid aluminium premium to a record $621/t. Indonesian HPAL nickel plants, which import roughly 75% of their sulphur from the Middle East, have already cut battery-feed output by at least 10%, while DRC leach operators face acid at $1,000–$1,400/t versus sub-$500 norms. Integrated sites with captive smelters, such as Ivanhoe’s Kamoa-Kakula producing 1,350 t/d of acid and selling Q1 volumes at $467/t then $725/t for June, are weathering the squeeze and in some cases monetising surplus, as European and US buyers also bid up Canadian aluminium to backfill lost Gulf supply.

    Technical Brief

    • Some Indonesian HPAL plants reportedly held only 1–2 months of sulphur inventory before curtailments.
    • DRC copperbelt imported about 1.3–1.4 Mt of sulphur last year, mostly via Middle East routes.
    • Shanghai Metals Market reports DRC sulphuric acid at $1,000–$1,400/t, versus sub-$500/t typical levels.
    • Ivanhoe’s Kamoa-Kakula smelter sold 107,700 t of sulphuric acid in Q1 at an average $467/t.
    • Kamoa-Kakula’s current acid output of ~1,350 t/d equates to about 60% of smelter design capacity.
    • Europe sourced ~1.3 Mt, or 21%, of its primary/alloyed aluminium imports from the Middle East in 2025.
    • Quebec’s aluminium export share to the US fell from 95% to 78% QoQ, with Europe rising to 18%.
    • Aluminerie Alouette redirected output sharply, lifting European sales from 4% to 57% of production in one quarter.
    • Alcoa diverted about 100,000 t of Canadian aluminium away from the US to alternative markets, mainly Europe.

    Our Take

    Wood Mackenzie has also been flagging energy‑linked cost pressure elsewhere in our coverage, with BMO using its data to show that Brent above $100/bbl can lift copper cash costs by ~16%, so the current sulphur and sulphuric acid squeeze on Congo copperbelt and Indonesian HPAL operations compounds an already tight margin environment for copper producers.

    The exposure of Indonesian nickel ‘battery‑feed’ output to sulphuric acid supply, alongside Indonesia’s role in producing more than half of the world’s nickel, dovetails with Wood Mackenzie’s lithium and broader battery‑metals work, where it projects structural deficits and heavy capex needs; disruptions here likely sharpen OEMs’ interest in geographically diversified critical‑minerals offtake such as the US Smackover Lithium deal covered in March 2026.

    Middle East aluminium’s 9% share of global smelting capacity and Europe’s 21% import dependence from the region echo Wood Mackenzie’s separate analysis of Venezuela’s stranded aluminium chain: both suggest that policymakers and traders in Europe and North America may revisit high‑capex restart or greenfield options in politically aligned jurisdictions as a hedge against Gulf‑related supply risk.

    QME 2026 in Queensland: decarbonisation and electrification takeaways for mine engineers

    The Queensland Mining and Engineering Exhibition (QME) returns to Mackay in July 2026 with a sold-out show floor, signalling strong demand from OEMs, technology vendors and contractors to showcase new equipment and digital systems. Organisers are centring the conference program on decarbonisation, mine electrification and automation, including low‑emission haulage, battery‑electric underground fleets and data‑driven maintenance. For site engineers and managers, QME 2026 offers concentrated access to suppliers and case studies tailored to Queensland’s coal and critical minerals operations, from Bowen Basin open pits to emerging North West Minerals Province projects.

    TECO MAX Ex d motor for underground coal mines: selection notes for engineers

    Specifying TECO’s MAX Ex d motor for underground coal mines centres on matching Ex d flameproof certification, insulation class (e.g. Class F/H windings) and available voltages to methane- and dust-laden headings with continuous duty. The AEMBXZ-TECO flameproof motor is designed for coalface and roadway equipment where restricted access limits maintenance intervals and thermal margins become critical. Engineers must balance frame size, starting torque and permissible temperature rise against hazardous area zoning and site supply (typically 1000 V or similar) to avoid derating and premature insulation failure.

    The reliability issue miners overlooked: maintenance lessons for fleet engineers

    Underground hard-rock mines are seeing development jumbo productivity eroded by repetitive maintenance on feed rail ropes, which are being replaced at increasingly short intervals long before outright failure. Crews are adapting work patterns around these stoppages rather than addressing the root cause, normalising frequent shutdowns and masking the true reliability problem in shift reports and KPIs. The case signals that reliability engineering in mobile fleets must target chronic, sub-failure component issues – such as rope wear mechanisms and lubrication regimes – not just catastrophic breakdowns.
