Mechanics of In-situ Leaching Attempt at Understanding Using Experiments and ModelsHerbert Einstein MIT Global Summit on Mine Tailings Innovation© EinsteinMechanics of In-situ Leaching BackgroundIn-situ leaching and tailings In situ leaching is being used Bulk: Rock Salt, Potash From internal surfaces: Uranium, Copper, Gold In situ leaching Can reduce but not eliminate tailings Leaching is often used in tailings deposits© EinsteinMechanics of In-situ Leaching IntroductionIn-situ leaching on internal surfaces in the ground Needs an opening in the ground: Natural Opening such as pores or fractures Artificially created opening (widening an existing one or crating a new one Need medium going through opening Needs medium to remove/transport mineralsTo understand the mechanics of all this we will show with exp
