Waste gangue represents a headache for all coal mines – it contaminates product, wastes hoisting capacity, and piles up on the surface as an environmental liability. Yangcheng Coal Mine in Shandong, China, faced an even greater challenge. Raw coal ash content reached 42.08%, and approximately 4 Mt of coal reserves were trapped beneath surface buildings – unrecoverable by conventional methods. The mine produces 350,000-400,000 t of gangue annually, straining the main shaft and creating dust, leachate pollution, and land occupation. The traditional solution would be to hoist it up and dump it. However, MeiTeng Technology, together with Haina Technology and…

Barrick Mining (B) is facing growing resistance from major shareholders over Chairman John Thornton’s plan to take some of the gold producer’s most valuable North American assets public, Bloomberg News reported Sunday. The proposed initial public offering would include Barrick’s (B) Nevada operations, its Fourmile discovery and a mine in the Dominican Republic. Barrick (B) would retain majority ownership while selling a minority stake to public investors. Portfolio managers at Van Eck Associates, Mackenzie Financial and Franklin Equity Group have opposed the strategy. Some argue existing Barrick (B) shareholders would effectively surrender part of their exposure to the company’s best…
In Afghanistan’s northeastern Badakhshan province, dozens of excavators operate day and night to extract gold from the mountains where villagers and their livestock once roamed. Thousands of miners are deployed across the Shiwa area, about 50 kilometres (30 miles) northeast of the provincial capital Faizabad, extracting gold for investors nationwide. Some residents in the area have profited from the gold rush, only to regret it later, such as farmer Muhammad Amin. “Before, the river was deep, the water was clean,” said the 74-year-old from Pul-e-Ziri Ban valley. Since mining got underway, “the water of the river is not drinkable; you…
Missouri S&T is among the universities included in a new $100 million federal initiative designed to strengthen the U.S. critical minerals workforce. The U.S. Department of Energy announced the Providing Opportunities for Specialized Education in Critical Technologies initiative Friday, Aug. 7. The program aims to double the number of graduates nationwide in mining, minerals and related technologies within two years. Funding will support scholarships, curriculum development, teaching tools and other efforts to increase the number of students pursuing degrees in mining-related fields. “Missouri S&T has educated generations of engineers and scientists who have helped meet our nation’s mineral needs, and this federal…
President Donald Trump announced over $2 billion in funding towards American mining on Friday, August 7th. The funding will go towards new mining projects, battery materials and rare earth alternatives. President Trump also highlighted over $180 million dollars towards mining education and training. President Trump says these investments are to strengthen the American mining industry, protect supply chains and reduce the use of foreign materials. “Over the past 18 months, our administration has signed or approved more than 160 Minerals deals worth nearly $40 billion. Today, the United States is opening new mines at the fastest pace. And we opened…
Hecla Mining Company Aug. 4 reported that the Greens Creek mine in Southeast Alaska continues to anchor the company’s current and future position as North America’s premier silver producer. Over the first six months of 2026, Greens Creek produced 4.23 million ounces of silver – along with 31,509 oz of gold, significant quantities of zinc and lead, and a little copper. With gold and base metals more than covering operating expenses at Greens Creek, the cost to produce each ounce of silver during the first half of this year was roughly negative $7. As a result, during the first six…
Global mining was once the quiet bedrock of industrial economies. Today, it is in the throes of a seismic shift. Driven by an insatiable appetite for minerals—cobalt for batteries, copper for electrification—the industry finds itself at a perilous crossroads. A confluence of surging demand, aggressive corporate consolidation, and a disturbing rise in human rights abuses paints a contradictory picture of our transition to a sustainable future. Projected to reach $3.5 trillion by 2032, the mining sector faces a harsh financial reality. Revenues for the top 40 mining companies fell by 7% in 2023, with another 6% drop anticipated in 2024.…
A resident evacuated from his street following ground movement linked to historical mining work says he expects his family will never return to their home. More than 250 people from 97 homes in the village of Coalsnaugton, Clackmannanshire, were told to leave their homes after the ground movement was discovered in May. An eight-week investigation by the Mining Remediation Authority (MRA) at the four affected streets has confirmed that the issue is related to past mining work. Aaron Anderson, who has three children including 11-year-old twins with autism, says he now “firmly believes” his house will be condemned and demolished. UK Energy…
Critical Mineral Accelerator could receive up to $160M over 10 years to advance mineral discovery, processing technologies and workforce development in Alaska Alaska’s vast critical mineral endowment is serving as the foundation of a new federally backed innovation coalition aimed at transforming discoveries in the laboratory and field into technologies, businesses, and jobs. On July 14, the U.S. National Science Foundation selected the University of Alaska Fairbanks-led Critical Mineral Accelerator Engine to receive $15 million over its first two years. If the Alaska coalition meets a series of performance milestones, it could receive as much as $160 million from NSF…
