ISR MINING.
What is Insitu Recovery (ISR) Mining?
GTI Energy is focused on defining economically viable ISR amenable uranium resources in Wyoming. ISR recovery is the lowest cost & least environmentally damaging form of uranium mining especially when an alkaline leach and ion exchange (IX) processes are utilised.
LOWEST COST AND LOWEST IMPACT URANIUM MINING.
ISR Mining.
Low environmental impact ISR mining, also called Insitu Leach (ISL) or Solution Mining, uses an alkaline or acid “lixiviant“ solution*, injected & extracted using a series wells to leach subterranean ores.
After the lixiviant is injected, the uranium-bearing solution is pumped to the surface & recovered in a processing plant. Uranium pregnant solution from production wells is pumped or trucked to a treatment plant where uranium is recovered typically using resin/polymer ion exchange (IX) or solvent extraction (SX). Clean water is reinjected.
* Alkaline leach & IX recovery are generally considered to be more environmentally friendly
