The main objective of this study was to clarify the inprinciple feasibility of electrokinetic in situ leaching of gold from finegrained porous media. We designed a series of laboratory experiments, monitored the temporal evolution of solution compositions, and analyzed the experimental results through processbased numerical modeling.
Uranium mining Wikipedia
The health effects discovered from radon exposure in unventilated uranium mining prompted the switch away from uranium mining via tunnel mining towards open cut and insitu leaching technology, a method of extraction that does not produce the same occupational hazards, or mine tailings, as conventional mining.
WellField Mechanics for InSitu Mining
consequently, the number of insitu mining operations is steadily increasing. Insitu leach mining can be done to extract a variety of di!erent products including potash, uranium, copper, gold and silver. Extraction can be accomplished using one of two methods; the welltowell recovery method discussed here, or stope leaching, a
Insitu_leach
Insitu leaching (ISL), also called insitu recovery (ISR) or solution mining, is a process of recovering minerals such as copper and uranium through boreholes drilled into the deposit. The process initially involves drilling of holes into the ore deposit. Explosive or hydraulic fracturing may be used to create open pathways in the deposit for solution to penetrate.
