Red mud waste to stronger cement: Sulphate activation delivers 7.33 MPa compressive strength
China’s growing red mud waste problem could offer an opportunity for the construction industry, as new research has demonstrated how aluminium industry residue can be converted into stronger cementitious materials. The study found that sulphate activation using flue gas desulphurisation gypsum achieved a compressive strength of 7.33 megapascals (MPa), more than double that of untreated mixtures. Researchers also identified the fractal geometry of microscopic pores as a potential indicator of material strength. The findings could support efforts to develop low-carbon construction materials from industrial waste, including red mud generated during alumina refining. However, the results also highlight a key engineering trade-off: the activation method that delivered the highest compressive...
243% rise in US-bound aluminium scrap: METLEN calls for a more competitive Europe
Europe’s aluminium scrap exports to the US have risen by 243 per cent, highlighting a growing concern over the continent’s access to strategic raw materials as it pursues recycling, decarbonisation and industrial competitiveness. Evangelos Mytilineos, Executive Chairman of METLEN, raised the issue, linking scrap outflows to the broader challenges facing European industry, energy security and strategic autonomy. Aluminium scrap outflows raise industrial concerns Mytilineos referred to the contrasting US tariff treatment of aluminium products, i.e., a 50 per cent tariff on primary aluminium, compared with zero tariff on scrap . With European aluminium scrap exports to the US increasing by 243 per cent, he questioned whether Europe could strengthen its industrial base while allowing valuable...

Speira launches CORIS high-purity aluminium range with purity levels of up to 99.9999%
German aluminium producer Speira has launched CORIS, a new product label for high-purity aluminium designed for advanced technology applications, including semiconductors, electronics, aerospace, medical technology and electrification. The CORIS range covers aluminium purity levels from 99.9% (3N) to 99.9999% or higher (6N+). Speira said the products are designed to meet the growing demand for materials with high electrical and thermal conductivity, precision and reliability. The company controls trace elements at parts-per-million (ppm) levels to maintain consistent material quality and performance. High-purity aluminium is used in applications where even small amounts of impurities can affect the material's properties. Join the fourth edition of webinar " Hedging for recyclers - Become...
Aluminium prices return to February levels as supply-chain pressures persist
London Metal Exchange (LME) three-month aluminium prices have returned to just above USD 3,000 per tonne, close to their levels in early February, before US and Israeli military operations against Iran began. However, the apparent stability in prices masks continuing pressure across the physical aluminium supply chain, following Iranian missile attacks on Gulf smelters and disruptions to shipping through the Strait of Hormuz. Almost 3 million tonnes of aluminium production capacity has been knocked out by the disruptions. Eight months later, the market appears relatively unconcerned, with traders relying on rising output from Indonesia and increased Chinese exports of aluminium products to compensate for the shortfall until Gulf smelters recover and shipping through the Strait of Hormuz...
Metro Mining cuts 2026 bauxite shipment guidance to 6.5m WMT amid operational challenges
Metro Mining has lowered its 2026 bauxite shipment guidance to 6.0–6.5 million wet metric tonnes (WMT), following below-plan performance in September at its Bauxite Hills Mine in Far North Queensland, Australia. The revised outlook factors in ongoing mitigation measures, mine productivity improvements, channel maintenance and potential weather-related constraints as the company seeks to maximise shipments before its planned February maintenance shutdown. The revised guidance was considered by Metro Mining’s Board of Directors on October 19, following the company’s September operational update issued on October 12. The company acknowledged investor disappointment after a challenging year, while maintaining that it is working to improve operating performance and deliver bauxite to market at...
Mount Ridley Mines files second Selectro patent to target industrial metals recovery
Australia’s Mount Ridley Mines is expanding its Selectro processing technology beyond critical minerals, with a second provisional patent application targeting industrial feedstocks such as bauxite and potentially opening new licensing and partnership opportunities. Mount Ridley Mines Ltd (ASX: MRD) has lodged a second provisional patent application for its proprietary Selectro hydrometallurgical technology, seeking to protect an adapted version of the process designed to recover metals from industrial feedstocks. Filed on October 15 2026, with IP Australia through its wholly owned subsidiary, Mount Ridley Tech, the application follows the company's initial Selectro patent filing in August 2026. The new application covers an adaptation of the technology in which the reagent molecule has...
WEEKLY: China alumina slips again as stocks rise; RMB 2,500-2,620/tonne seen near term
Domestic alumina spot prices edged lower last week, though trading activity picked up modestly. On the supply side, China's operating alumina capacity stood at around 98.9 million tonnes per year recently. One Guangxi refinery with a normal run rate of 2.3 million tonnes per year curtailed another production line, bringing current operating capacity down to 1 million tonnes per year. Separately, a newly commissioned alumina project in Guangxi has begun shipping finished product. The plant started feeding on September 21 and is now in a phase of quality optimisation and ramp-up, targeting full production next month at around 2 million tonnes per year. With industry margins compressing further, higher-cost operators face mounting pressure; coupled with recent weather-related disruptions in...
October 20, 2026 SMM daily inventory data of aluminium ingots in three regions
As of October 20, SMM statistics show domestic aluminium ingot social inventory across the three regions stood at the 450,000-million-tonne level, down further from the previous trading day, marking six consecutive working days of destocking. By region, all three regions saw destocking, with Guangdong and Wuxi posting relatively notable declines, while Gongyi edged down, and the scope of destocking expanded from the prior period. Overall, post-holiday cargo pick-up by downstream users remained steady, and inventory across the three regions continued to be absorbed, supporting spot premiums.
