In-situ leaching technology for uranium deposits

Kazakhstan possesses the world’s largest resource base of proven industrial uranium reserves. The article discusses geological features and provides a theoretical justification for technology in-situ leaching (ISL) deposits in Republic Kazakhstan. Explored reserves amount to about 1 million 560 thousand tons uranium. presence significant reserves, well-explored deposits, well-developed mining processing facilities, as well current situation on world market predetermine prospects development industry republic. When preparing by ISL method, an important role is given choice schemes opening with production injection wells. location wells exploited reservoir depends morphological characteristics reservoir, hydrogeological conditions productive horizon geotechnological parameters experimental work. Experimental work necessary step substantiate main preparation method (well layout, installation filters, productivity solutions, solution lifting means, consumption indicators reagent, etc.). performance that determine effectiveness application include: rate; average concentration solutions; reagent consumption; degree extraction from bowels; volume consumed unit ore mass (ratio L:S). based results Grant funding ip ??09561616 "Development scientific technical foundations deposits".
