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...

Rusal-owned Aughinish Alumina in Ireland faced a $167 million loss

Aughinish Alumina, a bauxite processing firm at Limerick in Ireland owned by the Russian aluminium giant Rusal, reported a loss of 167 million U.S. Dollars in the last year, as per the newly filed accounts. This is a decrease from the 378 million U.S. Dollars loss in 2021. The Irish operation on the Shannon Estuary faced challenges, losing key customers in Europe and expressing concerns about its ability to continue due to the impact of the geopolitical crisis in Ukraine. Despite a rise in revenue to 853.5 million U.S. Dollars from $784.5 million U.S. Dollars, the plant's output declined by 13 per cent. The accounts reveal that Rusal's business suffered from E.U. and U.S. sanctions following the geopolitical issues between Russia and Ukraine, leading to higher production costs,...

October 2023 alumina production in China records a dip of 1.6% M-o-M due to poor ore supply

According to the Shanghai Metals Market, China’s metallurgical-grade alumina production stood at 6.842 million tonnes, down by 1.6 per cent month-on-month but up by 2.5 per cent year-on-year. Daily average output in the said month was 220,700 tonnes, down by 3,700 tonnes from the previous month. The decrease in China’s alumina output from the earlier month owes to a tight supply of bauxite in Guangxi and Henan, roasting maintenance, and production cuts due to carbon emission reduction policies in Shandong. However, the country’s cumulative production from January to October 2023 grew by 2 per cent year-on-year, reaching 66.264 million tonnes. By the end of October, China’s installed alumina capacity was 100 million tonnes, operating capacity 80.68 million tonnes, and operating rate 80.7...

Century Aluminum reports power generation disruption at Jamalco refinery; suffers a loss of about US$22 million

Century Aluminum Company, the owner of Jamalco, said on Wednesday, November 8, that the malfunction of the power generation unit at the Clarendon-based refinery caused a loss of about US$22 million. Explaining the incident, president & CEO of Century Aluminum Jesse Gary said a power disruption resulted in an equipment failure at the refinery, which led to partial production for a portion of September and all of October. The loss translates to $3.4 billion in local currency. Jamalco expects to recover almost two-thirds of the total loss from insurance. Gary added that Century Aluminum had to fly in engineers from the manufacturer to address the cause of the incident and find a long-term solution. “The impact of the Jamalco equipment failure in the third quarter was approximately US$16.9...

Vedanta's breakthrough in the bauxite refining process

Vedanta, India's largest aluminium producer, has achieved a significant breakthrough in bauxite refining, a pivotal step in aluminium production. In a collaborative effort with the Indian Institute of Technology Kharagpur (IIT KGP), the company has developed an innovative method to substantially reduce the generation of bauxite residue, commonly called red mud. This pioneering process stands out for its remarkable accomplishment as it reduces bauxite residue by 30 per cent. It achieves this by eliminating iron values while simultaneously enhancing the yield of alumina. Moreover, this approach significantly reduces the total organic content in bauxite during the alumina refining process, ultimately curbing energy consumption. Vedanta Aluminium has been actively engaged in finding ways to...

Rusal to secure 30% stake in Chinese alumina company in $261.6 million deal

On October 24, 2023, the Russian aluminium giant and one of the world's leading low-carbon aluminium producers, Rusal, disclosed the news to acquire a 30 per cent equity stake in Hebei Wenfeng New Materials (HWNM), a Chinese alumina producer, for $261.6 million (RMB 1.91 billion). However, as stated by the company, the pending deal is subject to approval from Chinese authorities and consent from HWNM's creditors, enabling Rusal to acquire alumina at a competitive price. Rusal's shift towards procuring alumina from China directly responds to the export ban imposed by Australia on alumina and bauxite destined for Russia in March 2022. This ban was enacted as part of the sanctions by Western countries against Russia following the Ukraine-Russia geopolitical crisis. HWNM presently possesses...

The first boiler at Worsley Alumina shifts to natural gas

South32, a diversified mining and metals company, successfully converted the first coal-fired boilers to natural gas at its Worsley Alumina operation in Western Australia. This conversion is a significant step toward reducing the greenhouse gas (GHG) emissions generated by the operation. The Worsley Alumina operation comprises a bauxite mine near Boddington and an alumina refinery near Collie. The alumina produced in the refinery is distributed to smelters worldwide, including South32's Hillside smelter in Richards Bay, South Africa, and the Mozal smelter in Mozambique. The operation relies on boilers to generate steam critical for the alumina refining process. The conversion work for the boiler began in May and successfully transitioned to a gas-fired boiler in late September. The formal...
