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...

SINTEF's HARARE project aims to recover metals from red mud and copper slag

In the metallurgy industry, waste slag frequently contains valuable materials in low concentrations. Large areas of valuable land are used to house reservoirs containing hazardous waste. SINTEF, a research organization, now want to use hydrogen to convert this waste into a resource. SINTEF headquartered in Trondheim, Norway, is one of Europe's largest independent research organisations. It was founded in 1950 that conducts contract research and development projects. The world intensely needs metals, and realizing the so-called green transition depends on obtaining both the scarcer metals and those for which we have a plentiful supply. Nevertheless, when metals are recovered from minerals, it often ends with waste by-products. In addition, this waste may have significant environmental and...

Suvo Strategic Minerals acquires 26% stake in sustainable HPA production company Dingo

The Australian hydrous kaolin producer and exploration company Suvo Strategic Minerals has finally completed the acquisition of a 26 per cent stake in Dingo, an Australian-owned business that plans to make high-purity alumina (HPA) using recycled feedstock. Through a private placement of 220,000 fully paid ordinary shares at an issue price of $1 per share, the firm purchased Dingo for a total of $220,000. “Australia’s Federal Government recently added HPA to the critical minerals list as part of the 2022 Critical Minerals Strategy, citing broad-ranging economic and strategic importance. The global demand for HPA in powder form is expected to grow to 187,000 tonnes per annum by 2028, this growth is likely to be stemmed by supply limitations leading to a potential spike in prices as supply...

ARENA report unveils sustainability plan charted by big Australian alumina producers for net-zero by 2050

ARENA report unveils sustainability plan charted by big Australian alumina producers for net-zero by 2050

Australia could emerge as a leader in net-zero alumina refining worldwide if it obeys a plan developed by three major producers, Alcoa, Rio Tinto, and South 32. Together, the three organisations have developed a detailed road map that ensures net zero emissions by 2050. The report was published by the Federal Australian Renewable Energy Agency (ARENA) on November 22. Australia exports the most considerable quantity of alumina in the world and also produces ample bauxite. Refining activities in Australia cause up to 3% of the country's total greenhouse gas emissions. With the rising need for cleaner and greener aluminium in the western market, Australia has to think of other alternatives to make its products acceptable in the electronics or automobile sector. This calls for newer advanced...

Vedanta Alumina endorses Waste-To-Wealth MSMEs in Odisha

India's leading premier metallurgical grade alumina producer, Vedanta Alumina, Lanjigarh, is encouraging Waste-To-Wealth MSMEs in the Kalahandi district of Odisha. It has been supplying lime grit to local brick manufacturers, enabling the circular economy to turn industrial waste into value-added products. In the production of alumina, lime grit is produced by refining bauxite. The product can be used for several purposes, such as whitening paper, poultry feed, and even as a substitute for gypsum. The Vedanta Alumina refinery in Lanjigarh produces about 10,500 tonnes of lime grit every year, out of which nearly half is repurposed within the refinery. Another industrial by-product created by the company is fly ash, which is generated during thermal power generation. However, to ensure...

AMPRI researchers find new application of red mud as X-ray shielding tiles

Red mud, also known as bauxite residue, is one of the most underused industrial wastes created during the Bayer process used to process bauxite into alumina. However, with time, more than 700 red mud applications have been patented by scientists, out of which only a few have been adopted by the industry due to reasons like cost, poor public acceptability, environmental concerns, etc. One such application was recently made by the Bhopal, India-based research institute, CSIR Advanced Materials and Processes Research Institute (AMPRI). The researchers developed a method for turning red mud into X-ray shielding tiles using a ceramic process by including a certain weight proportion of high Z material and binder that is both environmentally friendly and economically feasible.

Sanctions against Russian aluminium company may lead to revenue losses for Jamaica

In the current fiscal year, the Jamaican Government estimates the value of mining and processing earnings from bauxite and alumina to be $507 million (JMD$77 billion), seven per cent more than the fiscal year 2020-2021. Jamalco is expected to reopen its operations in August 2022. The US and European sanctions linked to the Russia-Ukraine geopolitical crisis are again eyeing UC Rusal. This Russian aluminium conglomerate owns a major share of local alumina production, Windalco. Jamaica's mining and quarrying industry contracted by 62.5 per cent last year due to the fire that closed the Jamaica Alumina Company (Jamalco) plant in August 2021. Russian aluminium imports were expected to rebound, but now the US is considering restrictions. Other companies, such as US producer Alcoa, lobby for...

Alcoa lowers its outlook for alumina and bauxite shipments

The Pittsburgh-based industrial production and the world's eighth-largest aluminium producer, Alcoa, is lowering its outlook for alumina and bauxite shipments on the ground of demand contracts and reducing output. According to the Q3 earning report, the company anticipates alumina shipments to range from 13.1 million tonnes - 13.3million tonnes (t), a dip of 500,000 tonnes. This lower production level results from the company's San Ciprián refinery's 50% reduction in production, or 800,000 tonnes per year, to reduce its losses from higher natural gas prices. The Australian refineries of Alcoa are also expected to minimise shipment volumes. Due to lower demand from Australian refineries, the bauxite shipment estimates for the year have been reduced by 1 million tonnes to 43-44 million...
