Abstract
A modular solvent extraction plant for extracting metal from a metal are is provided. It includes a stage-wise, plug flow contactor that mixes an aqueous solution and an organic solvent solution into a mixed emulsion, a reactor to further mix the solutions, a separator for breaking up the emulsion into an aqueous solution and an organic solution, and a loaded organic coalescer that removes aqueous entrainment. It may also include a raffinate coalescer that removes organic entrainment, a second stage-wise, plug flow contactor that mixes an electrolyte solution with the organic solution from the loaded organic coalescer to form a second mixed emulsion, a second reactor, a second separator for breaking up the second emulsion, and an electrolyte coalescer. An organic scrub station may be used in place of the loaded organic coalescer. The contactors, reactors, separators, and coalescers can be mounted on movable structures.
