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...

Rio Tinto takes $1.7 billion hit: Alumina refineries write-off attributed to Australia's decarbonization scheme

The global mining and metal giant Rio Tinto has expressed concern that the expenses associated with renewable energy could severely impact Australia's industrial prospects. This comes in the wake of the company's absorption of a significant $1.2 billion loss and depreciation related to its alumina refineries in the last six months. Surprisingly, Yarwun, the very alumina refinery that Australia's Climate Change Minister Chris Bowen chose as the venue to announce the emissions reductions scheme in January, is now experiencing severe financial losses. The scheme, aimed at curbing emissions, poses a significant threat to Australia's aluminium production sector. Yarwun is no exception, as it entered into deep financial debt. As part of the initiative aimed at achieving net-zero emissions in...

Surefire unlocks milestone: Produces 4N HPA from Victory Bore

The Australian-based mineral-exploration company Surefire Resources has made its way onto the global stage for battery and LED markets by confirming 99.99 per cent pure alumina in test work utilising waste rock from its 100 per cent-owned Victory Bore vanadium mine, located roughly 400 kilometres east of the Western Australian port of Geraldton. The business announced that it has manufactured the critical high-purity alumina (HPA) standard known as "4N" - alluding to the four nines in the purity % measurement. Surefire's relevance stems from the company's now-proven ability to utilise waste from Victory Bore to manufacture 4N HPA . Others have traditionally depended on pricey high alumina-content metals to improve feedstock grades and, as a result, final product purity. Currently, 99.992%...

Top 8 alumina-producing countries and companies in the world

Top 8 alumina-producing countries and companies in the world

Alumina is essential for the production of primary aluminium. It is obtained from bauxite ore through the Bayer process and serves as the primary feedstock in the Hall-Héroult process , which extracts the non-ferrous metal, aluminium from its powder form. Alumina production is energy-intensive but necessary due to its importance in primary aluminium production. Last year, the worldwide alumina output slightly increased from the previous year, reaching 139.2 million tonnes. Almost all of the alumina production, about 93.7%, came from metallurgical-grade sources, with only a small amount being chemical-grade. China was a major contributor to this increase in production, producing an estimated 78.8 million tonnes of alumina, making up around 57% of the global output. Some of the major...

China’s June'23 alumina production dips M-o-M to 6.46 million tonnes due to tight supply of raw material

According to the Shanghai Metals Market survey, China’s metallurgical-grade alumina production in June 2023 (30 calendar days) totalled 6.46 million tonnes, down by 1.22 per cent from 6.54 million tonnes in May (31 calendar days). The daily average production in the said month was recorded at 215,000 tonnes, reflecting steady output compared to the earlier month owing to operation resumption in Henan, Guizhou, and Chongqing, along with newly added capacity. On a year-on-year calculation, China’s alumina output in June stood 4.2 per cent lower due to the closure of alumina capacities in high-cost areas like Shanxi, Henan, and Inner Mongolia. At the end of the month, China’s installed alumina capacity was 100.25 million tonnes, with an operating capacity of 78.58 million tonnes. The...
