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

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...

Workers at NICHE Fused Alumina halt strike

After enduring 10 months of stringent cost-cutting measures, the recent announcement of NICHE Fused Alumina's new restructuring plan has pushed the workers to the brink. Following a relentless 6-day strike, they have temporarily suspended their movement, pending a pivotal consultation with the company's management. “The year 2023 was complicated for the company, which saw the number of its orders drop following production difficulties,” explained Jean-François Vicini, David Bourquenoud, Carine Francina, and Anthony Buttarello, elected officials from CGT. “The situation became financially delicate and a first reorganisation was announced on July 28 in order to limit costs. The temporary contracts were stopped and the fixed-term contracts expiring (i.e. around 20 positions), were not...

Four prominent alumina refinery projects in Guinea that demand attention

In an effort to address the challenges associated with the 'Mineral Wealth Paradox,' Guinea, a prominent global bauxite hub, has taken a proactive approach. The nation has mandated that bauxite mining companies submit proposals for the establishment of domestic alumina refineries as an integral component of their operations. This strategic move aims to optimize the benefits derived from its rich bauxite resources while minimizing the potential downsides of resource extraction. The Russian aluminium giant Rusal operates Guinea's sole active alumina refinery, the Friguia refinery. The alumina refinery is one of the largest employers in Guinea, and the facility's annual production capacity is around 650,000 tonnes. There are currently six companies with plans to establish alumina refineries...

Russia increases alumina imports from India

Russia increases alumina imports from India

In recent months, Russia has increased its imports of alumina, the primary aluminium feedstock, from India to supply its extensive Siberian plants. This strategic move has allowed Russia to diversify its supply sources, reduce its reliance on China, and lower production costs. Following its invasion of Ukraine, a significant aluminium producer, Russia faced a shortfall in alumina supply due to a suspended production facility in Ukraine and Australia's ban on alumina exports to Russia. While Russia maintains amicable relations with China, the surge in aluminium production in China has constrained price flexibility for Russia's alumina purchases. Rusal 0486.HK, the world's largest aluminium producer outside of China, needed to bridge this supply gap to sustain domestic production and...

Russia amplifies Indian alumina imports to reduce dependency on China and others

Russia's recent increase in alumina imports from India has caught the attention of the global aluminium industry. This strategic move serves multiple purposes, including diversifying its supply sources, reducing dependence on China, and lowering production costs. As per the Indian Commerce Ministry, India's exports of alumina to Russia leapt from nil in the parallel period of the previous financial year to an exponential 2.58 lakh tonnes in the April to February timeframe of the financial year 2022-23 (FY23). This development comes as Russia faces challenges in its aluminium production due to geopolitical mishaps. After the inception of the Russia-Ukraine crisis, the competitor of China and India in World aluminium production, Russia lost access to two critical sources of alumina. Alumina...

India govt. to establish cutting-edge red mud processing pilot plant by December 2024

The Government of India is taking a significant step towards using Rare Earth Elements (REE) by establishing a cutting-edge pilot plant. This facility will process 100 kg of red mud, a hazardous waste generated from the alumina refining process, and extract REE from it. It's worth noting that red mud poses significant environmental and health hazards. The plant is scheduled to become operational by December 2024. This initiative involves collaboration with renowned institutions such as the Jawaharlal Nehru Aluminium Research Design and Development Centre (JNARDDC) in Nagpur, the CSIR Institute of Metal and Materials Technology (CSIR-IMMT) in Bhubaneswar, the CSIR-National Metallurgical Laboratory (CSIR-NML) in Jamshedpur, and the National Aluminium Company Ltd (NALCO).

Alumina Limited posts a net loss (after tax) of US$43 million for H1 2023 owing to lower alumina output

Alumina Limited, an Australian holding company, declared its 2023 first half results ended June 30, 2023, reporting a net loss (after tax) of US$43 million, compared to a net profit after tax of US$168 million during the corresponding period of the last year. Alumina Limited holds 40 per cent share in Alcoa World Alumina & Chemicals (AWAC), a joint venture with Alcoa. Lower volume of bauxite and alumina output against increased production costs was the reason for the loss accrued by Alumina Limited. Alumina production at the end of June 30 stood at 5 million tonnes, down by 18.03 per cent from 6.1 million tonnes a year ago. Alumina realised price was $361 per tonne, while cash cost of production was $319 per tonne. Alumina Limited’s CEO, Mike Ferraro, rightly pointed out, “The alumina...

China’s alumina output drifts 1.5% higher Y-o-Y in July citing mixed production traits in August

According to SMM data, China's metallurgical-grade alumina output during July was 6.869 million tonnes, with a daily production average of 222,000 tonnes, a surge attributed to the phased release of newly added capacity and the conclusion of maintenance in several Guangxi region companies, leading to a gradual resumption of production and an uptick in daily production. Year-on-year data reveals a 1.5 per cent increase in alumina production this July relative to the same period last year, primarily due to the input from newly commissioned alumina production capacities. As of the end of July, China's built alumina capacity reached a volume of 100 million tonnes, with an operational capacity of 81.08 million tonnes, culminating in a nationwide utilization rate of 81.1 per cent.
