In Situ Leach and Conventional Uranium-Recovery Methods ...
From 1972 through 1985, uranium recovery in Texas was dominated by conventional mining and milling. More recently, companies (licensees) have been using In Situ Leaching (ISL), a process that makes possible the recovery of uranium without disturbing the natural surface, generating dust, or producing waste known as tailings.Get Price
NRC: Uranium Recovery
This happens either in a uranium mill (the next step in processing ore from a conventional mine) or during in situ recovery (ISR). For that reason, the NRC regulates in situ recovery facilities (as stated above), as well as uranium mills and the disposal of liquid and solid wastes from uranium recovery operations (including mill tailings ).Get Price
Uranium acid mine drainage - Wikipedia
Uranium acid mine drainage (UAMD) refers to acidic water released from a uranium mining site using processes like underground mining and in-situ leaching. Underground, the ores are not as reactive due to isolation from atmospheric oxygen and water. When uranium ores are mined, the ores are crushed into a powdery substance, thus increasing surface area to easily extract uranium.Get Price

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.Get Price

Heap leaching - Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...Get Price

Talk:In situ leach - Wikipedia
In-situ leach vs. brine recovery. Someone has added a section on lithium brine mining. It is my understanding that this involves pumping up brines which naturally contain dissolved lithium. In-situ leach, on the other hand, involves dissolving substances which are naturally present in a solid state.Get Price
In Situ Leaching of Copper Economic Feasibility
This model was developed to calculate the blast design parameters and fragmentation cost for in situ leaching operations as a function of the deposit parameters. The model is based on blasting an ore zone or an ore zone plus overburden by either a coyote blast or a vertical blasthole system.Get Price
