Abstract The uranium required for power plants is mainly extracted by two methods in roughly equal amounts quarries underground and open pit and in situ leaching ISL Uranium mining by in situ leaching is extremely attractive because it is economical and has a minimal impact on the region s ecology
The Pinyon Plain Mine formerly known as the Canyon Uranium Mine had been closed for decades but was reopened by Energy Fuels Inc in 2024 Mining companies are seeking to open more uranium mines and mills The reopening of the Pinyon Plain mine may be the start of a new wave of uranium mining and processing throughout the Southwest
Nuclear reactor Uranium Mining Processing Uranium is extracted from ores whose uranium content is often less than percent one part per thousand Most ore deposits occur at or near the surface; whether they are mined through open pit or underground techniques depends on the depth of the deposit and its slope The mined ore is crushed and the uranium
Key Points • Uranium mining and processing are associated with a wide range of potential adverse human health risks Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise whereas other risks apply to the mining sector generally and still others are linked more broadly to large scale industrial or construction activities
An international team of researchers discovered that Harmony Gold Mining s gold and uranium Moab Khotsong mine in South Africa hosts billion year old groundwater a finding that sheds new
The company said it is also preparing the Whirlwind Colorado and Nichols Ranch Utah mines to commence uranium production within one year which it says would increase its uranium production to over 2 million pounds of U3O8 per year starting in 2025 "if strong market conditions continue as expected"
Advancements in mining machinery have meant deeper and deeper open pits have been viable over the last century Small open pits dug by hand are known historically Examples of how uranium mining has evolved to effectively manage impacts with case studies contrasting old and new practices and outcomes are highlighted by OECD NEA 2014
The Benefits of Automation in the Uranium Mining Process Automation is quickly becoming a cornerstone in the uranium mining process providing numerous benefits to industry operations One notable advantage is the increased safety that automated and remote controlled systems offer by reducing the need for workers in hazardous environments
In uranium mines the radiological hazards are primarily due to the airborne radionuclides which consist of radon and its short lived daughter products Po 218 Pb 214 Bi 214 and Po 214 Radon Rn 222 is an inert gas therefore it passes freely into and out of the lung
The ISL mining process can be defined as the recovery of uranium from its host formation by the circulation of lixiviants using injection and production wells from the surface Wellmer and Becker Platen 2002 Iaea 2018a Iaea 2018b Zhou et al 2019 Wen et al 2020 Although this technology needs further development for performing low grade uranium
EQUIPMENT MATERIAL PROCESSING Agglomeration Many of the world s top mining companies have come to rely on FEECO for our agglomeration drums; FEECO ore drums are installed in some of the world s largest and most environmentally advanced Agglomeration drums are used in the uranium heap leaching process to provide a more
Additionally Cameco is recognized for its environmentally friendly way of mining uranium Cameco also has a strategic partnership with Brookfield Asset Management Ltd NYSE BAM that gives the company a 49% interest in Westinghouse Electric Company This will be a key strategic move as demand for nuclear reactors will likely increase
Uranium mining open cut and underground and milling Peter H Woods in Uranium for Nuclear Power 2016 Trends and alternatives Advancements in mining machinery have meant deeper and deeper open pits have been viable over the last century Small open pits dug by hand are known historically

Activity concentration of any radionuclide of uranium decay chain >1 Bq/g or K 40 >10 Bq/g Public exposures exist Exposure to radon & radon progeny is controlled or above reference levels •Uranium mining typically has activity concentrations >1 Bq/g •Graded approach required based on exposure risk
6 Through ISL uranium miners can extract uranium ore without using the more expensive traditional mining techniques Almost 60% of the world s uranium comes from ISL mined uranium Similar to traditional solid bulk analysis of uranium ore it is critical to mining efficiency to determine the concentration of uranium in the liquid solution
Now the first drum of uranium has been successfully processed Boss said it will accelerate plans to increase the production rate and mine life at Honeymoon The current mine plan utilises 36 million pounds of the project s total million pounds JORC compliant resource half of which is already covered by the existing mining licence

Cigar Lake Project in Saskatchewan Canada was the largest uranium producing mine in the world producing approximately 4 403 tonnes of uranium and an estimated million metric tons per annum mmtpa of Run of Mine ROM in 2021 The Cigar Lake Project is owned by Cameco Corp and is due to operate until 2029 The second largest uranium producing mine with an
Uranium for Nuclear Power Resources Mining and Transformation to Fuel discusses the nuclear industry and its dependence on a steady supply of competitively priced uranium as a key factor in its
The fields of machine learning ML and artificial intelligence AI have recently seen a number of highly publicised successes with systems capable of matching and exceeding human level performance on a range of computer games using only the pixels on the screen Mnih et al 2015 significant improvements to language translation Wu et al 2016
