  • CONTAINMENT AND REMOVAL SYSTEM FOR DRAG AND DREGS IN A DECANTER USED IN THE SOLVENT EXTRACTION PROCESS
    Publication number: 20230364529
    Abstract: Containment and removal system for drag and sludge that constitutes a barrier to contain drag from aqueous to organic and from organic to aqueous, which can be used in a settler (settler) for solvent extraction processes, being designed to filter sludge, generate the sedimentation of aqueous droplets in organic and/or organic droplets in aqueous, and/or favor the coalescence of aqueous droplets from the organic phase, avoiding contamination due to the presence of drag and sludge.
    Type: Application

  • Process for improving phase separations in solvent extraction circuits
    Patent number: 8298510
    Abstract: The addition of a compatible metal salt crystal to the organic solution entering the mixer(s) in the solvent extraction stage(s) and/or the stripping stage(s), or to the emulsion mixture of the organic solution and the aqueous solution in the mixer(s), or to the mixture of the organic solution and the aqueous solution in a settler tank(s) following the mixer(s) in the solvent extraction and/or stripping stage(s) following the leaching of metal values from the ore containing that/those value(s) into an aqueous solution, and prior to the further refining of those values in processes, such as electrowinning, during mining operations for those metal values in order to improve the phase separation of the organic phase and the aqueous phase, and to promote the removal of contaminants from the organic phase.
