Uranium production based on in situ leaching (ISL)
Oral
ISL uranium mining technology was developed independently in the USSR and USA in the early 1960s. The Soviets adopted the acid while the US alkaline leaching system. The major advantages of ISL over conventional mining are: little surface disturbance, no tailings or waste rock, economical mining of lower grade ores, minimal radiation exposure, lower capital and operational costs. The principal...

Uranium production based on in situ leaching (ISL)
Oral
In the second half of the 60s production of Uranium from low-grade ores by in-situ leaching (ISL) feasibility was proved. It fundamentally changed the situation in the raw material base in Kazakhstan.
Rapid development of ISL uranium mining in Kazakhstan was promoted by the availability of large sandstone type deposits.
As of 1 January 2014, identified and prognosticated in situ uranium...

Uranium production based on in situ leaching (ISL)
Oral
The Nichols Ranch ISL Uranium Mine is located in the Powder River Basin of Wyoming, U.S.A. The mine is owned and operated by Uranerz Energy Corporation (Uranerz); a U.S. corporation headquartered in Casper, Wyoming. Nichols Ranch started operations in February 2014 and is the newest uranium mine to go into production in the United States. The uranium being extracted is hosted in a...

Uranium production based on in situ leaching (ISL)
Oral
The “Khiagda” mine in the Republic of Buryatia is the only ISR mine in the world where ore mining is performed in a permafrost region. Its raw material source is deposits of the Khiagdinsky ore field having geological reserves of uranium to 48 thousand tonnes. The ore field is a part of the Vitimsky Uranium ore district with reserves of 100 thousand tonnes. This is the most promising region...

Uranium production based on in situ leaching (ISL)
Oral
This paper describes recent advancements in exploration technologies for sedimentary-hosted uranium deposits as basis for improved model-based planning and optimization of in-situ re-covery (ISR).
High-resolution shallow (<500m depth) seismic in combination with refraction tomography is used for high-fidelity imaging of true-depth stratigraphy of sedimentary formations, tectonic faults and...

Uranium production based on in situ leaching (ISL)
Oral
Drilling pattern and quantity of technological (injection and production) wells in the uranium in-situ leaching is determined by the projection of ore deposit to the daylight surface, structure and hydrogeological characteristics of ore-bearing deposits and given well field productivity. The difference between the structure of production and injection wells lies in that the upper part of...

Uranium production based on in situ leaching (ISL)
Oral
Operational efficiency of in-situ leaching (ISL) deposits essentially depends on the geotechnical well conditions. In most cases, during operation of such wells the decrease of well flow rate and injectability is observed, which is caused by the new formation of salts and clay particles that are deposited on the screen and in the near-screen area. In this connection, there is a need for...
