Red mud-based concrete cuts carbon footprint by up to 79.8% in Trinity College Dublin study

Researchers at Trinity College Dublin are testing a new type of concrete made using red mud, a residue from alumina refining. The project, supported by Enterprise Ireland and carried out with Gannon Eco and McGrath Quarries, has progressed from laboratory research to trials using industrial batching equipment. The university reported on 22 October that the geopolymer concrete formulations reduced the carbon footprint by 67.8–79.8 per cent against a CEM II-A/L cement reference. The comparison included raw material supply, transport and manufacturing. To know the futuristic market and value proposition of red mud, explore the report " A Comprehensive Analysis of Bauxite Residue (Red Mud): Sustainability, Resource Recovery and Strategic Recommendations " Laboratory tests also found that the...

Alumina steady-to-soft as spot tightens, deepening losses fail to spur cuts

Alumina steady-to-soft as spot tightens, deepening losses fail to spur cuts

Domestic spot alumina prices edged down slightly last week amid flat trading activity. Recent alumina price movements were mainly attributed to earlier concentrated restocking by downstream buyers, which has led to accumulating inventories at rail stations and smelters. Coupled with supply-side maintenance-driven output cuts that are still building, readily available spot volumes have tightened relatively. Only sporadic tender deals were heard recently, leaving prices in a temporary steady phase. On the bauxite front, domestic ore prices saw limited movement last week. Supply-side bottlenecks are unlikely to ease in the near term, with mines prioritising captive supply, leaving little excess spot material available. For imported ore, freight rates rebounded slightly and consecutively last...

AL Circle Analysis: Guinea’s 150Mt bauxite cap, China’s import swings, US tariffs draw aluminium Q4’26

The global aluminium supply chain is facing a series of changes that extend from bauxite mines and alumina refineries to smelters, regional premiums and finished-metal trade. In 2026, the market’s direction is being shaped not only by production volumes but also by freight costs, export restrictions, shifting Chinese demand and tariffs. Developments across Guinea, Australia, China, Europe and North America point to a market where access to supply is increasingly as important as the availability of raw materials. Bauxite supply: Guinea’s cap meets a well-stocked China, but is it stable? Guinea remains central to the seaborne bauxite market, with its shipment connections to China demonstrating the importance of reliable logistics. A new sea-rail route has enabled a Guinea bauxite shipment...

Iran’s annual alumina output drops 2% driven by a fall in Q4; Chinese help to boost production

According to the latest report revealed by Iranian Mines and Mining Industries Development and Renovation Organization (IMIDRO), Iran produced 225,942 tonnes of aluminium oxide, commonly known as alumina, in the past year 1401 (ended March 20, 2023). That reflected a drop of 2 per cent from the previous year despite a growing trend till the first nine months (March 21-December 21, 2022). As per the data shared by IMIDRO, Iran’s alumina output stood at 176,239 tonnes during March-December , reflecting a 1 per cent rise year-on-year from 175,284 tonnes. In the final quarter of the Iranian calendar year, Iran’s alumina production dwindled by 13.40 per cent quarter-on-quarter from 57,394 tonnes to 49,703 tonnes unlike the sequential rise in output in the third quarter by 1.50 per cent.

Glencore agrees to buy equity stakes in Alunorte, ready to pay $700 million to Hydro

Norsk Hydro said on Thursday that it would sell a 30 per cent share in Brazilian alumina refinery Alunorte and a 5 per cent investment in bauxite producer Mineracao Rio do Norte to Swiss miner and trader Glencore. However, in a recent update, Glencore plans to pay about $700 million for the equity interests upon the conclusion of the agreement in the second half of 2023, according to a separate statement, which will provide the miner and dealer with a proportional offtake of the metal. "The growing decarbonisation trend is driving demand not only for the mass production of batteries that require the raw materials which Glencore produces but also for primary aluminium as a strong, lightweight manufacturing metal," said Robin Scheiner, head of alumina and aluminium at Glencore.

Alcoa brings force majeure to an end for its Western Australian alumina operation

According to an S&P Global Commodity Insights report on Wednesday, April 26, Alcoa has withdrawn the force majeure for its Western Australian alumina business. The news came after Alcoa spokesperson confirmed the matter. But before that, there was hearsay in the market regarding the force majeure lift from several sources as early as April 21. Alcoa first notified of the force majeure to its alumina customers in January 2023, resulting from the impact of lower natural gas supply in Western Australia, cutting about 30 per cent of output at the Kwinana alumina refinery . Per the company’s 1Q2023 results, Kwinana refinery was being operated at 20 per cent or 438,000 tonnes per year less capacity as of March 31, as one of the five digesters remained offline. Although the gas supply situation...

Update: Century Aluminium pays US$1 to acquire a major part of Jamalco; Full transaction price is a mystery

In line with the report published last day that Century Aluminium agreed to buy a 55 per cent stake in Jamalco, the US-based primary aluminium producer signed a purchase contract with Noble Group Holdings Limited for US$1. The deal is expected to close by the end of April 2023, but the full transaction price is unknown. This update was published after Century said in filings, “A wholly owned subsidiary of Century will acquire General Alumina Holdings Limited, a Noble subsidiary and owner of Noble’s 55 per cent interest in Jamalco, for US$1. The transaction is expected to close by the end of April 2023.” Although the deal price is not explained, it implies the transaction may have cleared Noble of liabilities for Jamalco going forward.

Hydro strikes a deal with Glencore to develop Alunorte alumina refinery

Hydro has struck a deal with Glencore under which Glencore would purchase 30 per cent of the Brazilian alumina refinery Hydro Alunorte and 5 per cent of the Brazilian bauxite production Mineraco Rio do Norte (MRN). Glencore will buy an extra 40 per cent of MRN, now controlled by Vale. Hydro will purchase this 40 per cent stake from Vale and promptly sell it to Glencore on a back-to-back basis, following which Hydro will no longer possess a stake in MRN. The bauxite arrangement between Vale and Hydro will be terminated, and Glencore will continue to supply about 30 per cent of Alunorte's long-term bauxite demand from MRN after the transactions. Hydro's 2025 plan, unveiled in 2020, set a clear goal of increasing profitability and driving sustainability across the organisation. As part of...

IMMT scientists find rare earth elements in Odisha red mud

On April 3, scientists from the Institute of Minerals and Materials Technology (IMMT), Bhubaneswar, reported the estimated quantity of rare earth elements that can be recovered from red mud in Odisha, a toxic byproduct generated in abundance during the processing of bauxite into alumina. Rare earth elements are crucial components for electronic and electric systems, devices used to produce green hydrogen, and electric vehicles. It is a known fact that red mud contains rare earth elements, but the amount of elements present depends on the origin of bauxite and how it is processed into alumina. A recent study published in Current Science on March 25 revealed that the fine-grained content of red mud at NALCO’s Damanjodi alumina refinery contained 433 ppm of rare earth elements like cerium,...

Global alumina market witnessed significant developments in 2022

The Chinese alumina production capacity was approximately 76.6 million tonnes as of November 2022. AlCircle’s latest report ‘Global Aluminium Industry Outlook 2023’ states that the nation's alumina refineries used about 79 per cent of their capacity in November 2022 compared to 81 per cent in October 2022. Higher Covid infection rates in China during that time, production restrictions due to environmental issues, and lower operating rates contributed to the reduction. China is anticipated to have produced 6.7 million tonnes of alumina in November 2022, out of which 95 per cent of which was metallurgical quality. Australia is still the world's largest alumina exporter and the second-largest producer. The nation's production was projected to have increased from 20.1 million tonnes in...
