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...

Pinjarra alumina refinery faces downtime amid natural gas supply disruptions

The natural gas supply to the Pinjarra alumina refinery in Australia, which has an annual production capacity of 4.7* million tonnes, has been unexpectedly disrupted on December 10, 2024. This interruption caused a power outage and a substantial caustic soda spill at the facility. However, full production capacity is expected to be restored within 7-10 days. Independent news and insight into energy, industry and climate in Western Australia, Boiling Cold reported that a company spokesperson stated the incident disrupted process flow, and clean-up operations for the spills began promptly.

NALCO shares stoop low under international alumina pricing influence

NALCO shares stoop low under international alumina pricing influence

Shares of NALCO saw a sharp decline of over 7 per cent on Thursday, December 12, dropping to their lowest point of the day. Answering to the question of why several key factors have weighed in on this nationally and internationally. The primary trigger appears to be the movement in alumina prices, a critical raw material for aluminium production. NALCO, being one of the leading players in the alumina market, is particularly sensitive to these transnational price fluctuations, especially as the state-run company sells a significant portion of its alumina on the open market. Post alumina prices surge from US$600 to US$820 per tonne in the past few months, they have cooled off recently to around US$700 per tonne contributing as a major factor to this decline. There is also the reduced demand...

The increased capacity and operating rate drove China’s monthly alumina output in November. Month-on-month, the...

Red mud generation trend across major countries, 2018 to 2023

Red mud generation trend across major countries, 2018 to 2023

Bauxite residue, commonly known as red mud, is a highly alkaline by-product generated during the Bayer process of alumina extraction from bauxite ore. With global alumina production steadily increasing to meet the demands of various industries, the volume of red mud produced has surged correspondingly, posing significant environmental and management challenges. The red colour is due to the presence of iron oxides (along with other oxides). The multifaceted nature of red mud demands an immediate and thorough understanding to mitigate its adverse effects and harness its potential benefits. Red mud contains unreacted minerals, metal oxides, and caustic soda, making it toxic if not managed properly. Its disposal has traditionally involved storage in large containment areas, which poses risks...

Saint-Gobain pushes for tariffs on sol-gel alumina abrasive imports from China

Saint-Gobain Ceramics & Plastics, Inc. has officially filed a petition seeking to impose antidumping and countervailing duties on sol-gel alumina-based ceramic abrasive grains imported from China. The move is aimed at addressing what the company claims are unfair trade practices that have impacted the U.S. abrasive grain market. According to the petition, the investigation will focus on specific ceramic abrasive grains made from at least 94 per cent aluminium oxide (Al₂O₃) and potentially mixed with compounds such as titanium dioxide, silicon dioxide, and zirconium dioxide, among others. These grains, known for their advanced crystalline microstructure and superior abrasive capabilities, differ significantly from conventional fused grains.

Court rules in favour of BALCO; says vanadium sludge exempt from royalty

In a significant judgment, the Chhattisgarh High Court in India has quashed the Korba Collector's (the highest officer of the revenue department in the district) order that imposed a hefty royalty of INR 863.18 lakh (USD$ USD 1.04 million) on Bharat Aluminium Company (BALCO) Limited for vanadium sludge. The High Court Single Bench presided over by Justice Bibhu Datta Guru, found the order to be legally unsustainable, citing an improper examination of both legal and factual grounds. The crux of the Court's decision rested on whether vanadium sludge— a by-product generated during the removal of impurities from bauxite as it is processed into alumina—could be classified as a mineral liable for royalty. Justice Guru ruled that vanadium sludge does not fall within the definition of a mineral,...
