The technique of in situ leach (ISL) uranium mining is well established in the USA, as well as being used extensively in Eastern Europe and the former Soviet Union. The method is being proposed and tested on uranium deposits in Australia, with sulfuric acid chemistry and no restoration of groundwater following mining.

In 2001, an in-situ leach (ISL) mine, the Beverley uranium mine, began operating in the northern Flinders Ranges in South Australia. The mine is owned by General Atomics, a US-based company, and managed by its subsidiary, Heathgate Resources. In 2014, Beverley was put into care-and-maintenance, while the nearby Beverley Four Mile began producing. ISL involves pumping acid into an aquifer. This ...

to the modern mining era. The in-situ recovery processes applied to the uranium mines in the Curnamona Province of South Australia are arguably delivering world-leading environmental outcomes across commodities, and are applied in pursuit of uranium. In contrast, the rare earth mining boom in some developing countries such as China and the lithium mining boom in South America are reminiscent ...

This mine should not be allowed to operate in sight of an important cultural and sacred site. Instead of extending its life by using acid leaching, the mine should be shut down. The history of in situ leach uranium mining shows that there will be leaks and spills of the sulfuric acid. Spills at some modern mines have been extensive, and you ...

Issues at Operating Uranium Mines and Mills - Australia

In situ leach mining (ISL) is a method of uranium mining where hundreds of wells are drilled in a “grid pattern” over an ore body that is located in a groundwater aquifer. Water mixed with sodium bicarbonate concentrate is pumped down into the aquifer, across the uranium ore bed, and them up and out other wells. The mining solution is injected into the aquifer

In-situ_leach - chemeurope.com

In-situ leach for uranium has expanded rapidly since the 1990s, and is now the predominant method for mining uranium. In this technology, uranium is leached from the in-place ore through an array of regularly spaced wells and is then recovered from the leach solution at a surface plant. The chemical solution is injected into a drilled hole into the rock at the periphery of the uranium deposit ...

The uranium plume is brought to the surface with a series of “production wells” and processed for shipment to enrichment facilities. In the US the production life of a well field is roughly 1 to 3 years 1. However, groundwater restoration efforts can last for decades. Permitting and regulation. In situ recovery process.

Review of environmental impacts of the acid in-situ leach ...

The first uranium ISL in the US was in the Shirley Basin in the state of Wyoming, which operated from 1961-1970 using sulfuric acid. Since 1970, all commercial-scale ISL mines in the US have used carbonate solutions. In-situ recovery involves the extraction of uranium-bearing water (grading as low as .05% U 3 O 8). The extracted uranium solution is then filtered through resin beads. Through an ...

ISL produces 90% of the uranium mined in the US. Two more ISL projects are in licensing and proposal stages in the US, and two in reclamation in 2006. Significant ISL mines are operating in Kazakhstan and Australia. The Beverley uranium mine in Australia uses in-situ leaching. ISL mining produces around 21% of the world's uranium production.
