In Situ Leach (ISL) or Solution Mining is a third alternative mining technique, quite different to conventional open cut or underground mining and milling operations. The ISL process can be applied to the extraction of uranium, copper, silver, gold, nickel and many other metals. For an ore deposit to be amenable to ISL it must occur within
In-Situ Recovery of Uranium has become a well-established mining method over the past 40 years. ISR offers a low-cost, environmentally sound process of extracting metals from deposits. ISR projects now populate the entirety of the topthird of the lowest uranium production cost facilities globally.
1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, uranium. The Guidebook also does not discuss waste rock dumps, tailings, heap leach materials (for gold and silver operations), and dump leach materials (for copper leach operations).

The 10 Largest Uranium Mines The world's biggest uranium producers in 2010 Olympic dame is Australia's largest mine and is characterized by a multi-mineral ore body that produces uranium as a well as copper, gold and silver. the South Inkai uranium deposit is an in-situ leaching operation that is operated by the Betpak-Dala joint
Unfortunately, in situ leaching can also be very harmful if the solution leaks into the water supply. There are plenty of examples of past leaks at in situ leaching mines (Colorodoans against resource destruction, 2008).
FACTSHEET Uranium mining and milling By Lizzy Bloem. Uranium is extracted from ore at uranium mills and at in situ leach (ISL) facilities. Uranium is also obtained as by-product from non-conventional uranium plants, like the phosphate industry. To excavate the rocks, the traditional mining methods of drilling and blasting are used
