Ablative Arc Mining for In-Situ Resource Utilization

In situ leach or leaching (ISL) or in situ recovery (ISR) mining has become one of the standard uranium production methods. Its application to amenable uranium 

The submersible pumps initially extract native groundwater from the host aquifer prior to the addition Remote ion exchange. In Situ Recovery (ISR) is a low-impact method of metal recovery that involves the dissolving of a value metal from ore in situ into a fluid and pumping this fluid to the surface for processing. IN-SITU LEACH URANIUM MINING IN THE UNITED STATES OF AMERICA: PAST, PRESENT AND FUTURE D. H. UNDERHILL* Nuclear Assurance Corporation, Norcross, Georgia, United States of America Abstract Commercial in-situ leach (ISL) uranium mining in the United States began in the mid-1970s. Both acid and alkaline leach systems were evaluated. 2021-02-10 · In-situ leaching technology is now widely used to exploit ion adsorption rare earth ore, which has caused serious environmental problems and deterioration of mining soil ecosystems. However, our knowledge about the influences of mining operation on the microbiota in these ecosystems is currently very limited. (j) "In situ mining" means as defined in W.S. § 35-11-103(f)(iv) (2003).

Uranium In Situ Leaching : The Case Against Solution Mining i Preface The mining and export of Australian uranium has been a controversial issue for many years, and will continue to remain an intense political issue for many more years to come. With a depressed world uranium market, the mining industry has been seeking to In-situ leaching itself is not a new technology. It has been used for Uranium mining for over 50 years and today nearly half of all Uranium mining is done by this method.

Surface mining leaves toxic tailings ponds. In contrast, in situ uses more specialized techniques such as steam-assisted gravity drainage (SAGD). "Eighty percent of the oil sands will be developed in situ which accounts for 97.5 percent of the total surface area of the oil sands region in Alberta."

As with other types of hard rock mining there are several methods of extraction. In case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of 0.05 %. We previously proposed an in situ fluidized mining tech-nique to achieve in situ exploitation and conversion of deep underground coal resources.37-40 This technique involves transforming deep, solid coal into electric energy or gaseous/ liquid state substances in situ, followed by transporting the 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-Situ monitoring equipment and software works together to make it easier and more cost effective to collect, access and manage the data you need.
