摘要： Copper is preferentially extracted from iron in an aqueous feedstock solution containing dissolved copper and iron values by contacting the feedstock solution with a water-immiscible organic solution comprised of a hydrocarbon solvent and a compound of the formula I wherein R5 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, a C7-22 aralkyl group, a halogen, OH or —OR6 wherein R6 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, a C7-22 aralkyl group; R1 is hydrogen, or a C1-22 linear or branched alkyl or alkenyl group, a C6 aryl group or a C7-22 aralkyl group; R2-R4 is hydrogen, halogen, a linear or branched C6-12 alkyl group, —OR6 wherein R6 is a C1-22 linear or branched alkyl group, a C2-22 linear or branched alkenyl group, a C6 aryl group, or a C7-22 aralkyl group to form an aqueous phase comprised of iron and an organic phase comprised of the hydrocarbon solvent and a copper-extractant complex wherein the copper-extractant complex is soluble in the hydrocarbon solvent. The R2-R5 groups are chosen so that the copper-extractant complex is soluble in the hydrocarbon solvent. After the extraction stage is completed and the organic and aqueous phases separate, the organic phase is substantially free of iron and/or an iron-extractant complex.

摘要： Toxic cyanide and anionic metal species are removed from aqueous alkaline solutions by contacting the aqueous alkaline solutions with an extractant compound which is capable of being protonated at a pH of 9 or above. Whereby the anionic metal species is extracted from the aqueous alkaline solution, subsequently stripping the metal values from the extractant and recovering the metal species, preferably by electrowinning. The process is useful in a flotation process in which a recycled aqueous process stream is employed in that the toxic cyanide ion and anionic metal species are removed prior to recycling of the aqueous process stream for flotation.

摘要： A process for the separation of naphthalenesulfonate-based carbonyl condensates from water is provided. The process comprises contacting a mixture comprised of water and a naphthalenesulfonate-based carbonyl condensate (preferably a material selected from the group consisting of formaldehyde condensates of naphthalenesulfonic acids, formaldehyde condensates of lower-alkyl substituted naphthalenesulfonic acids, and mixtures of two or more of such materials) with a liquid organic phase comprised of a lipophilic non-quaternary amine to form an aqueous phase depleted with respect to said mixture of naphthalenesulfonate-based carbonyl condensate and a liquid organic phase enriched in naphthalenesulfonate-based carbonyl condensate. The process further comprises separating said aqueous phase depleted with respect to said mixture of naphthalenesulfonate-based carbonyl condensate and said liquid organic phase enriched with respect to naphthalenesulfonate-based carbonyl condensate. The process further comprises stripping the enriched liquid organic phase by contacting with an alkaline stripping solution to regenerate the cationic lipophilic amine, recycling the alkaline stripping solution for contacting with a further portion of enriched liquid organic phase. The alkaline stripping solution may then be treated by nanofiltration to separate inorganic salts from the polymeric naphthalenesulfonate-based carbonyl condensate.

摘要： The invention is a process and an apparatus for removing metal contamination from soil. In the method, the soil is treated to produce soil with a small particle size. The particulate soil is then separated into a coarse fraction and a fine fraction. The coarse fraction and the fine fraction are contacted with a leach solution in separate contacting zones to remove the metal contamination from the soil, the metal is removed from the leach solution and the leach solution recycled to the leaching zones.
