Rio Tinto has just released its results for 2025, which highlight a mining giant that is steadily moving into metals that will drive the energy transition. Under the leadership of CEO Simon Trott, the mining giant increased output and profits due to a combination of operational excellence and improved financial discipline. Rio Tinto’s consolidated revenues […]

Trump administration officials said on Friday that there would be no changes to President Donald Trump’s sweeping tariffs steel and aluminum and thousands of products made from the metals unless Trump announces them. A White House official, responding to a Financial Times report that the administration was planning to scale back tariffs on some steel […]

The Australian Federal Government officially approved a seven-year extension for the Middlemount Coal Mine, a joint venture between Peabody Energy and Yancoal. This approval allows the mine to continue operations until 2044, extending its previous end-of-life date from 2037. Key project details The extension, formally known as the Middlemount Southern Extension Project, involves expanding the […]

In early 2026, the Kamoa-Kakula Copper Complex in the DRC is moving toward the formalization of its Phase 4 expansion. While Phase 3 is already in operation, Phase 4 is a strategic “next step” designed to replicate the success of the current facilities. Phase 4 expansion details The Phase 4 expansion is planned as a […]

Efficient mining operations rely on a seamless integration of equipment, processes, and skilled management. Among the most critical components in mining is ore crushing, which directly affects the downstream efficiency of mineral processing, including ore beneficiation. High-performance ore crushing machines play a pivotal role in ensuring consistent production, minimizing operational costs, and enhancing the overall […]

Most of us entering the mining industry today will still be here 30 years from now. Many tailings facilities built today will require monitoring for more than 100 years. That gap is not accidental. It is a design decision. Tailings management is not merely a storage problem. It is a century-scale risk management challenge. The […]

The global economic and social costs of landslides are increasing, with factors such as the intensification of climate change, urban development in marginal terrain areas, and aging infrastructure systems contributing to this trend. Existing approaches to slope monitoring, based on traditional concepts such as periodic manual surveys, single parameter measurements, and reactive responses to slope […]

The mining industry in Australia is one of the most resource-intensive sectors, requiring massive amounts of energy, water, and materials to maintain productivity. Concrete, as a foundational material for mining infrastructure—such as processing plants, tailings storage, and road networks—plays a crucial role in site development. However, conventional concrete production can consume significant amounts of water […]

The dynamic nature of construction and infrastructure projects across Latin America has made the mobile stone crusher plant an indispensable asset for on-site aggregate production. Its ability to relocate and process materials directly where they are needed offers tremendous logistical and economic advantages. However, this very mobility and the inherent complexity of crushing operations introduce unique safety […]

Australia’s Pilbara Ports said on Friday that Port Hedland, the world’s biggest iron ore export hub, and the Western Australia ports of Ashburton, Cape Preston West, Dampier and Varanus Island were cleared due to the threat of a cyclone. Pilbara Ports said Australia’s weather bureau warned that a tropical low off Western Australia’s coast could […]

The partnership was started in 2023 and is still going strong today, highlighting Rio Tinto workers, local communities, and Québec-made, low-carbon, 100% recyclable aluminium. Rio Tinto today unveiled a new campaign called “Forged here,” which represents the next phase of its collaboration with the Montréal Canadiens. The commercial honours workers who manufacture aluminium made in […]

The U.S. government has agreed a financing deal worth $565 million with Brazilian rare earths miner Serra Verde, which includes the option to take a minority equity stake, the firm said on Thursday. The deal is part of a wide-ranging package announced on Wednesday by U.S. Vice President JD Vance to create a preferential trade […]

Data lives where people shouldn’t Underground mining has always demanded a difficult trade-off: the most critical data often lies in the dangerous places where people can not access safely. Stopes, ore passes, headings, and old workings hold essential information for production, reconciliation, and geotechnical confidence—yet accessing them safely has remained a persistent challenge. For years, […]
