In Situ Leaching or Recovery | Metallurgy & …
In situ leaching (ISL), also known as in situ recovery, is a low capital-cost method of extracting uranium, copper or potash from suitable deposits. A suitable deposit is one where the commodity is located in saturated permeable horizons or distinctive geological areas that are bounded above and below by impermeable strata. Either acid or alkaline solutions can be used to dissolve the metal ...
Thermodynamic Modeling of in Situ Leaching of …
In situ leaching (ISL) is the main mining method for sandstone-type uranium deposits. The thermodynamic model can provide important information to real project decision making. However, systematic thermodynamic modeling work is still lacking for uranium-containing systems. In this paper, a thermodynamic model for the uranium minerals–solution–gas system is established with reliable and ...

In Situ Leach and Conventional Uranium-Recovery …
Shows steps for the in situ leach-mining method to extract uranium from ore-bearing formations, including ways to protect the environment. Conventional uranium extraction methods are also discussed. 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 ...
Metal-Contaminated Soil Remediation: …
Phytoremediation, chemical leaching and electrochemical remediation are three techniques commonly used for the remediation of contaminated sites. Each of these techniques has its advantages and limitations. Due to the non-availability of enough arable land, the use of phytoremediation, though it is eco-friendly, would lead to food insecurity as it takes long period to clean a target site ...
In-Situ Leaching Materials Considerations - …
In-situ mining and in-situ leaching are synonymous processes employed to extract mineral values from the earth without removal of the ore body. These processes are, in fact, a combination of petroleum processes are, in fact, a combination of petroleum technology, ground water hydrology, corrosion chemistry, and hydrometallurgical engineering. The operational aspects of the process involve ...

Uranium mining by in-situ leaching - UCIL
IN-SITU LEACHING, provided some necessary geological and geo-technical conditions are met. IN-SITU LEACHING: The technique of in-situ leaching is a relatively unknown method in India, though it is largely practiced and successfully implemented in almost all mineral-rich countries of the world. Extraction in this method is accomplished through the dissolution of natural in- place metal in ...

Electrokinetic in situ leaching of gold from intact …
Electrokinetic in situ leaching (EK-ISL) is a novel in situ mining technology that uses an electric field to induce the migration of lixiviants through the subsurface to extract target commodities. Based on previous experiments with fine-grained unconsolidated material, this study assesses the feasibility of EK-ISL of gold from consolidated, unfractured, low-permeability ore material. Under ...

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.

In-Situ and Laboratory Investigation on Leaching …
The amount of leaching after such a short time indicated that a one-sided water pressure existed in combination with a permeable shotcrete. The reason for the water pressure was likely a partly unsuccessful grouting that created sections with leaking water. The permeable shotcrete could be a combined result of insufficient curing and the use of accelerators, and the effect of in-situ curing ...
Report on In Situ Uranium Mining - Larimer County, Colorado
In Situ Leaching and Open-pit Mining Currently in the United States, all ISL uranium production is with alkaline leaching chemistry using carbon dioxide or sodium-carbonate and oxygen (lixiviant). The most common acid used in ISL is sulfuric acid. Acid leaching was only used once in the United States (in Wyoming) but is used in other countries.
