“…Furthermore, it is crucial to emphasize that low-grade sandstone-hosted uranium deposits, which were previously economically unviable for extraction, can now be economically and efficiently mined using these two mining technologies. Regarding the heap leaching technology, some research has been conducted [27,[30][31][32][33][34]. Ghorbani et al have conducted a thorough and detailed review of its current development status, technological innovations, and future directions [32].…”

Uranium, a cornerstone for nuclear energy, facilitates a clean and efficient energy conversion. In the era of global clean energy initiatives, uranium resources have emerged as a vital component for achieving sustainability and clean power. To fulfill the escalating demand for clean energy, continual advancements in uranium mining technologies are imperative. Currently, established uranium mining methods encompass open-pit mining, underground mining, and in situ leaching (ISL). Notably, in situ leaching stands out due to its environmental friendliness, efficient extraction, and cost-effectiveness. Moreover, it unlocks the potential of extracting uranium from previously challenging low-grade sandstone-hosted deposits, presenting novel opportunities for uranium mining. This comprehensive review systematically classifies and analyzes various in situ leaching techniques, exploring their core principles, suitability, technological advancements, and practical implementations. Building on this foundation, it identifies the challenges faced by in situ leaching and proposes future improvement strategies. This study offers valuable insights into the sustainable advancement of in situ leaching technologies in uranium mining, propelling scientific research and practical applications in the field.

“…Since high-grade ores have been primarily mined, low-grade ores have become economically mineable. Approximately 80% of primary copper production comes from low-grade or poor sulfide ores (Robertson et al, 2005). Nearly half of the cobalt is produced as a byproduct of nickel/cobalt ore processing; a significant portion (35%) is produced from Central African copper-cobalt ore. Other primary sources, such as Moroccan cobalt-arsenic ores, account for the remaining 15% (Mills, 2014).…”

“…As a result, it was found that the efficiency of the process, apart from gold content, depends on the scale of heap leaching unit, content of clay minerals, stack height, ore stack ing method and a number of other factors. The main role is played by the content of clay fraction, which prevents the filtration of solutions, as well as trapping already dissolved gold [32][33][34].…”

There are the results of a study of the factors determining the formation and changes in the filtration properties of a heap leaching stack formed from pelletized poor sandy-clay ores. An analysis of methods of investigation of filtration properties of ore material for different stages of heap leaching plots functioning is carried out. Influence of segregation process during stack dumping on formation of zones with very different permeability parameters of ore has been established by experimental and filtration works. The construction and application of a numerical model of filtration processes in pelletized ores based on laboratory experiments is shown. By means of solution percolation simulation at different irrigation intensities the justification of optimal stack parameters is provided in terms of the geomechanical stability and prevention of solution level rise above the drainage layer.
