Process for the recovery of liquid extractant and acid from emulsions formed during metal recovery from acid solutions

摘要

A method of recovering liquid from an emulsion formed in a liquid-liquid contacting process, where the emulsion comprises at least one of the liquids entrapped by water-permeable membranes, comprises: admixing water and the emulsion in a volume ratio of water:emulsion of between 0.5 to 4.5:1 and raising the temperature of the admixture to between about 45 DEG C. and 99 DEG C., to cause water permeation of the membranes, causing them to disintegrate and release liquid, forming a three-phase composition consisting essentially of the two liquids and the solids.
