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...

China’s metallurgical-grade alumina output mounts to 77.68 Mt in 2022 amid energy price surge and pandemic outbreak

According to the Shanghai Metals Market, China’s metallurgical-grade alumina output in December 2022 (31 calendar days) stood at 6.43 million tonnes, reflecting a month-on-month rise of 2.2 per cent from 6.29 million tonnes and a year-on-year increase of 1 per cent from 6.36 million tonnes. But despite the growth in monthly production, the average daily output recorded a downfall of 2,500 tonnes or 1.2 per cent M-o-M from 209,800 tonnes to 207,300 tonnes in December 2022. The monthly growth in December was primarily due to one working day more than the previous month. However, on a year-on-year calculation, China’s daily average alumina output in December’22 recorded 2,000 tonnes or 0.97 per cent higher than 205,300 tonnes.

Alcoa to cut 30% production at Kwinana alumina refinery for natural gas shortage

Alcoa to cut 30% production at Kwinana alumina refinery for natural gas shortage

Alcoa Corporation, the world’s eighth-largest aluminium producer, announced on Monday, January 9, that it expects to cut nearly 30 per cent of production at its partially-owned Kwinana alumina refinery in Western Australia. Shortage of gas supplies is the reason behind the production cut, explained Alcoa. A unit of the refinery, majorly owned by Alcoa in a joint venture with Alumina Limited, has already been suspended, and the remaining refinery will face slow operational processes, said Alcoa in a statement. In December 2022, Australia government sought a 12-month price cap on gas and coal prices, but natural gas producers anticipated that might put supply at risk. Kwinana alumina refinery is currently using diesel to fuel its operations instead of gas, as a result of the shortage. Alcoa...

Chevron’s WA gas plant breakdown forces Alcoa to rely on diesel generators

Chevron has requested two more days to take care of the technical problems leading to a drastic breakdown at its Wheatstone domestic gas plant. This can be regarded as the third West Australian (WA) gas plant breakdown during the whole summer. All this turmoil has prompted Alcoa to ignite diesel generators to continue with their smelting activities. On January 8, WA Mines and Petroleum Minister Bill Johnston confined to sources that the Wheatstone plant supplying approximately 175 terajoules or about 17 per cent of West Australia’s domestic gas production, would halt operations until the break of Tuesday this week. The unprecedented breakdown has created a vacuum in WA’s energy supply chain. Mr Johnston made it known that he was “personally disappointed” by Chevron’s delay but “confident...

Lanthanein Resources accomplishes first air core drilling at Koolya kaolin high-purity alumina project

An initial air core first-pass drilling programme at Lanthanein Resources' Koolya Project in Western Australia has concluded after 599 metres of drilling and with unprecedented visual results.

Brazilian aluminium industry to benefit from Equinor's solar power project

Norwegian energy firm Equinor has reached a final investment decision for $430 million in Brazil's 531MW Mendubim solar project. It is a joint venture project between Scatec, Hydro Rein, and Equinor in Rio Grande do Norte. In a 20-year power purchase agreement, Alunorte, one of the world's largest alumina suppliers for the aluminium industry, has already agreed to buy about 60% of the PV project's electricity. However, the remainder will be sold in the Brazilian domestic market. There will be an annual production of approximately 1.2TWh, equivalent to 620,000 Brazilian households' electricity consumption. In addition, it is expected to generate more than 1,000 direct and indirect jobs during construction. Olav Kolbeinstveit, Senior Vice-President at Equinor Renewables Power and Markets,...

Alcoa breaks ground with a new bauxite residue processing unit in Brazil

Earlier in November, renowned aluminium producer from America, Alcoa Corporation, inaugurated a brand new bauxite residue processing unit in Brazil. The facility makes good use of water and land conservation methods that it had practised to perfection in Australia. The latest Poços de Caldas alumina refinery will use a press filtration system to reprocess the bauxite residue, or red mud yielded at the plant. This move will benefit the regional people who, without direct participation in any alumina unit, had to once pay hefty prices. Bauxite residue is extremely harmful to agriculture and cattle rearing, thus disrupting the local settlements in carrying on with their usual lifestyle. Plus, exposure to it for a long time may also cause respiratory diseases or much more harmful chronic...

Rising gas prices coupled with Ukraine-Russia geopolitical crisis pose a threat to Limerick Alumina Refining's job security

After talking with company bosses, Niall Collins, the Limerick TD and Minister of State has played down fears of job losses at Aughinish Alumina. According to the company's directors and auditors, the Ukraine-Russia geopolitical conflict and its economic impact are threatening the future viability of Rusal-owned West Limerick. Since the rise in gas prices in the year before the Ukraine invasion, the company has suffered a net loss of over €363 million. Now, these prices have increased again due to the conflict, putting the organization under immense pressure. As a result of the document, fears have again been raised for the nearly 500 employees at Europe's largest bauxite refinery, which produces 30% of the country's alumina, used primarily in aircraft.
