METHOD AND APPARATUS FOR MIXING GASEOUS OXIDANT AND LIXIVIANT IN AN IN SITU LEACH OPERATION Abstract of the Disclosure Method and apparatus for mixing a gaseous oxidant (e.g., oxygen) and a lixiviant (e.g., an aqueous carbonate solution ) at a downhole Location before the oxygen-saturated lixiviant is injected into a formation to be leached. The inven- tion involves eatablishing a mixing zone in the well by positioning a mixing means, comprising a housing, in the well at the downhole location. Lixiviant is flowed down the well and through a restrictive opening in the housing to substantially increase the flow velocity of the lixiviant. At the same time, gaseous oxidant is fed to the housing and is trapped therein by the increased velocity of the lixiviant and by packing material in said housing. The lixiviant flows through the trapped oxidant which, in turn, dissolves into the lixiviant to saturate same. Additional packing material is provided in the housing to remove undissolved oxidant from the saturated lixiviant before it is injected into a formation to be leached.
