Insitu mining is also called insitu leaching, insitu recovery or solution mining. The technique involves dissolving minerals using either an acid or alkaline leaching solution which is pumped through the ore body. The solution dissolves the uranium and then these uraniumrich fluids are pumped to the surface where the metal is extracted.

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and
