In-situ leach. In-situ leaching (ISL), also called in-situ 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.
The U.S. Nuclear Regulatory Commission (NRC) expects numerous license applications for new in situ leach (ISL) uranium recovery facilities (commonly known as in situ recovery facilities) in 2008 through 2010.To facilitate the agency's review of those applications, the NRC staff has prepared a Generic Environmental Impact Statement (GEIS), which addresses common environmental issues …
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.
In situ leaching. The aim of in situ leaching (or ISL for In Situ Leaching), sometimes named in situ recovery (or ISR for In Situ Recovery), is to dissolve metals such as copper or uranium directly into the deposit. With a series of injection and production wells, a flow of leaching …
In-situ leach. In-situ leaching (ISL), also known as in-situ recovery (ISR) or solution mining, is a method of recovering minerals like copper and uranium throughout boreholes drilled into the deposit. The process primarily involves drilling of holes into the ore deposit.
Cogema requests license renewal for restoration of Christensen Ranch / Irigaray in-situ leach uranium mine site, Wyoming On May 30, 2008, Cogema Mining Inc. requested a license renewal for its Christensen Ranch / Irigaray in-situ leach uranium mine site. The site is currently undergoing groundwater restoration.
Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2015 amounted to 60,496 tonnes. Kazakhstan, Canada, and Australia are the top three producers and together account for 70% of world uranium production. Other important uranium producing countries in excess of 1,000 tons per year are Niger, Russia, Namibia, Uzbekistan, China, …

in the leaching solutions for recovery in a reasonable period of time, and these should be a reasonable consumption of leaching reagents. 3. History of ISR In situ recovery (ISR)2 uranium mining technology was developed independently in both the USSR and in the USA in the late 1950s to early 1960s. It was developed in both countries using ...
Uranium ores are normally processed by grinding the ore materials to a uniform particle size and then treating the ore to extract the uranium by chemical leaching.The milling process commonly yields dry powder-form material consisting of natural uranium, "yellowcake," which is sold on the uranium …
In situ recovery (ISR, also referred to as in situ leaching or solution mining) may offer such a step-change approach. ISR refers to the recovery of valuable metals from ore deposits by the circulation of a fluid underground and the recovery of the valuable metal from the …
- Status of uranium in situ leach mining operations in May 1980 Encouraged by the apparent success of in situ uranium leach mining, companies have pilot tests in operation or under construction in other major uranium-producing States, such as Wyoming, New Mexico, and Colorado. As of
Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation, the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene

A short description of the in situ leaching/in situ recovery (ISL/ISR) uranium mining technique and other uranium mining techniques are included for completeness, even though, based on current knowledge of known uranium occurrences in ia, ISL/ISR is unlikely to be applicable.
In-situ leaching: Submarginal ores obtained by blasting; ore treated for 5 – 25 years with an operational capacity of 4 million tons of ore. Fig. 17.1 illustrates design aspects of heap bioleaching for uranium.
In-situ leaching is one of several leaching methods. In-situ or in-place leaching means that the metal values are leached directly from the ore without excavating the ore prior to leaching. Leaching reagents that dissolve the desired metals are pumped into the deposit through injection wells.

In looking at "Insitu uranium leaching" I believe a possible terrifying aspect is that DEPLETED URANIUM is used in the logging process and in the blasting cones when the "well" is fracked…the epi-thermal neutrons can react with the uranium deposit in such a way that ...
low cost operation. In addition, in situ leaching of uranium is more sensitive to good engineering management and attention to detail than other types of uranium mining. Prior to the operation of an in-situ leach mining facility it is necessary to collect data on: (1) geology, (2) hydrology, and (3) in-situ leaching mining impacts.

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.

In-situ leaching can transport uranium and thorium into groundwater or surface water at the processing site. High levels of TENORM have been found in the PLS of two in-situ leach operations in Arizona. Copper smelting and refining facilities produce 2.5 million metric tons (MT) of smelter slag and 1.5 million MT of slag tailings per year.
In situ leaching (ISL) is the dissolution and subsequent recovery of minerals from the subsurface by injection of a chemical solution. Because ISL of gold does not involve bulk rock mining, it has great potential to be substantially more environmentally friendly than conventional methods.
In situ leach (ISL) mining, also called in situ leaching or in situ recovery mining, has become a standard uranium production method, following early experimentation and use in the 1960s. Its application to amenable uranium deposits in certain sedimentary formations has grown owing to competitive production costs and low surface impacts.
