Rock breaking by CO2, also known as carbon dioxide rock breaking or gas expansion cracking, is a non-explosive technique used to break rocks in various applications, including mining, quarrying, and construction. But its effectiveness can vary depending on the specific rock type and its geological properties.

Rare earths ( Coming under the umbrella of Critical Minerals) power the world around us—smartphones, EVs, and even clean energy. But did you know they’re not as rare as their name suggests? In this post, we explore why rare earths are abundant yet so difficult to access. Learn about the challenges of mining, their environmental impact, and what the future holds. Please go through to understand how these essential elements shape our world—and why they’re key to building a sustainable future.

https://lnkd.in/gshyVmTZ is the process of extracting valuable minerals, metals, and other geological materials from the earth. It involves drilling, blasting, digging, and transporting these materials to the surface for processing. 

Mine the land for Critical Raw Materials (CRM’s), and/or, for Rare Earth Metals (REM’s), then dispose of these CRM’s / REM’s as wasted resources post use. Why? Promotion of a linear economy business model? Instead of mining these collective wasted resources (e.g. from ELV batteries, WEEE ….), let’s now extract them from the sea bed instead. We can see the environmental impacts arising on the land; what are the unintended consequences arising if mined from these depths? With these issues in mind, this BBC article should prompt a discussion. Views welcome. https://lnkd.in/evn3taxr

🌍️🏭️Imagine a society that is no longer emitting #CO2 into the #atmosphere by massively burning #fossilfuels... ... but instead, binds it and utilizes it as a valuable resource for innovative carbon-containing #materials. 💯Sounds promising. But also highly challenging. This is the goal of Empa’s new research initiative: Mining the Atmosphere. After having published a series of articles about the initiative, we are concluding this focus topic with special Bright Minds videos and a livestream featuring Nathalie Casas, head of the Department Energy, Mobility and Environment, and Peter Richner, head of the Department Engineering Sciences. In this video, learn why Nathalie Casas aims to go beyond #netzero and envisions a society that will successfully transition from a CO2-emitting society to a CO2-binding society. 💡 Livestream on Mining the Atmosphere, 25 April 13.30-14.00.

Interesting regarding constructing in mining!

OD6 Metals' (ASX:OD6) has achieved significant metallurgical recoveries of magnetic rare earth elements in recent test work at its Splinter Rock Project, anticipated to contribute to the Project's upcoming mineral resource estimate ⛏ 🇦🇺 "The results continue to show that the Splinter Rock Recoveries are as good as or better than the Brazilian-hosted Rare Earth plays that have gained so much attention over the last 12 months and continue to affirm that we are Australia’s premier clay-hosted rare earth deposit. "The Inside Centre recoveries of ~60% when combined with grades of between 1,400 to 2,200ppm TREO, across an extensive 2km by 1km areas, with substantial thicknesses between 20 to 77m, a low stripping ratio, plus low acid consumptions continue to be a standout for the company. “These metrics align closely with the essential value drivers we believe are crucial for the economic viability of clay-hosted rare earth projects both in Australia and globally. "At the Splinter Rock Project we have no private royalties, do not sit over farming land, are located in a known wind and solar renewable energy corridor, plus we are only a short distance to the major port of Esperance. "We look forward to these factors being considered as part of our future Mineral Resource Estimate upgrade scheduled for later this quarter," - OD6 Metals Managing Director Brett Hazelden #ASX #ASXNews #Investing #Mining #Markets #Exploration #RareEarths #REE #WA https://lnkd.in/d3Si8um2 Subscribe to the weekly Stock Market Newsletter www.themarketbull.com.au

Rare earth elements are at a critical juncture. If the US, Canada and other countries do not invest in mining and processing, we will be completely dependent on China for chips, military equipment, electric vehicles, and critical infrastructure. Stantec’s Brian Mashford and Greg Gillian were featured in North American Mining Magazine where they review recent developments in the North American rare earth elements industry. Rare earth elements will be needed for #ElectricVehicle production, #OffshoreWind energy generation, and more. Thank you, North American Mining magazine for highlighting this important topic. https://bit.ly/4f60KxT #StantecResources #EnergyTransition 🌎 ⚡ 🚗 💻

📢 Huge news for the marine sector and the future of deep sea mining 📢 I've been waiting a while to read this much anticipated paper from Sweetman Andrew of the Scottish Association For Marine Science ever since I heard about his talk last year at MASTS Scotland. The nodules that so many deep sea mining companies rely on for the production of batteries, may actually be producing oxygen through seawater electrolysis, and are key for deep-seafloor organisms. Which means deep sea mining may be far more harmful that anticipated. https://lnkd.in/d_Pyx2ht
