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.

2012-8-1  In situ or in place leaching (ISL or IPL) is therefore currently being investigated as an alternative to mine gold more sustainably and to make current uneconomic deposits mineable. ISL and IPL refer to the extraction of specific elements from a deposit by injecting a chemical solution (lixiviant) into the ore body through injection wells.

BERI ** INTRODUCTION: Uranium is commonly understood as a material storing a huge energy and its only commercial application is as nuclear fuel. But apart from its uses in nuclear power plants, the possibility of its use in nuclear weapons makes the material of strategic

The low concentration deposit of uranium, gold, boron and other minerals is mined by the In-Situ Leaching method. The hydrodynamic pressure equation, Darcy law, equation of mineral dissolution ...

2018-1-1  EK-ISL would involve the leaching of gold, in situ, using a lixiviant that is introduced via a set of wells. A voltage gradient is applied to transport the lixiviant through the orebody. The gold is leached and also transported towards a set of recovery wells. At the surface the gold is recovered and the lixiviant

The concept of leaching metallipherous ore deposits in situ to recover valuable metals from injected solutions has attracted research interest over many decades. Despite this, the technique is only employed commercially in the uranium mining industry with approximately 20% of global uranium production being recovered via this method (OECD1). A major attraction of such an approach is that it ...

Here, we propose a new approach, electrokinetic in situ leaching (EK-ISL), which combines two existing technologies: (i) in situ leaching (ISL), which comprises the application of a lixiviant to selectively dissolve target metal(s) from their ore without removal of its host matrix, i.e., without excavation, and (ii)

In situ leaching – what it is. ISL involves injecting chemicals, called “lixivants” into an aquifer that contains a uranium ore body (i.e. deposit ). The chemicals used are typically sulfuric acid or ammonium carbonate. Under natural conditions, these ore bodies are

In Situ Recovery (“ISR”) involves recovering minerals in place without long term negative impacts on the surface. The EnviroLeach solution is injected into the mineral deposit, which dissolves the minerals in a controlled process. The pregnant solution is then pumped to the surface for mineral extraction and solution regeneration.

2020-1-4  Can other minerals be mined using in situ leaching? While the immediate concern in South Dakota is in situ leach mining of uranium, the process has been used elsewhere to mine other minerals such as copper, gold, sulfur and several different types of salt. What do the new rules cover with regard to construction, operation, monitoring and

2020-10-22  In-situ 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 well-to-well recovery method discussed here, or stope leaching, a

In present work modeling of mineral extraction by the In-Situ Leaching (ISL) method is considered. The low concentration deposit of uranium, gold, boron and other minerals is mined by the In-Situ ...

waste form by mass. We propose a new approach, electrokinetic in situ leaching (EK-ISL), and demonstrate its applicability for a Cu-bearing sulfidic porphyry ore. In laboratory-scale experiments, Cu recovery was rapid (up to 57 weight % after 94 days) despite low ore hydraulic conductivity (permeability = 6.1 mD; porosity = 10.6%). Multi-

In situ stope leaching is an innovative mining system that reduces the surface impacts of conventional underground mining. As in any leaching operation, stope leaching requires hydrologic site characterization and control of leaching solutions. Several tracer tests, using sodium chloride (NaCl) in various concentrations, were

The correspondence shown in Fig. 4 between observed and simulated uranium recovery quantitatively confirms the conclusions of earlier investigators regarding the role of the low permeability mineralized zone in determining uranium recovery at the Hobson site. It is often possible to learn much about the leaching behavior of a large and complex field site by modeling a small portion of it ...

Uranium processing - Uranium processing - Leaching: Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. Acid leaching is commonly performed by agitating an ore ...
