Abstract
A dual packer injection leaching system with a dual packer assembly and a support structure. The dual packer assembly has an upper packer, a lower packer, and a high dispersion screen disposed between the upper packer and the lower packer. The dual packer assembly is configured to be disposed within a borehole in a leach pile. The support structure is configured to support the dual packer assembly within the borehole. A wire rope couples the support structure to the dual packer assembly. A pneumatic line is configured to inflate the upper packer and the lower packer, and an injection line is configured to provide leachate solution through the high dispersion screen. The dual packer assembly is configured to deliver the leachate solution through the high dispersion screen to an interval of the borehole bounded by the upper packer and the lower packer.
