The ore should occur in a generally horizontal bed underlain and overlain by a relatively impermeable stratum. 2. The host rock should have a good permeability. 3. The ore must be located below the water table. 4. The direction and velocity of regional water flow must be known. 5. The uraniumManual of acid in situ leach uranium mining technology,sandstone hosted uranium deposits amenable to ISL recovery are relatively widespread in the world. ISL technology recovers uranium using two alternative chemical leaching systems — acid and alkaline. Acid leach is the more widely employed and has historically produced a majority of the world’s ISL production.

In situ leach - Wikipedia

In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ. In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining. The process initially involves the drilling of holes into the ore deposit. Explosive or hydraulic fracturingm…blasting for in situ uranium leaching,blasting for in situ uranium leaching.

Uranium mining - Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan andResearch Status of the In-situ Blasting Leaching Method,The paper describes the current domestic uranium mining technology development situation,the status quo and the development trends of in - situ blasting leaching technology in uranium.With the development of the in - situ leaching technology,environmental protection,blasting technology,the following aspects of work should be carried out for the in - situ leaching blasting research:the in,blasting for in situ uranium leaching in south africa,INNOVATIONS AND TRENDS IN URANIUM ORE TREATMENT. 2.3 IN-SITU LEACHING PROCESSES ISL for uranium was developed in the,stopes broken by blasting and to old,to uranium in the South African gold-uranium
