Abstract: New chelate exchange resins capable of selective recovery of copper, nickel, and other valuable metals from an acidic aqueous leach liquor are prepared by reacting a crosslinked haloalkyl polymer matrix resin (I) with certain aminopyridines (II) to give a resin (III) ##STR1## with pendent methyleneaminopyridine groups attached to the matrix resin. Particularly useful resins are obtained by reacting chloromethylated styrene-divinylbenzene copolymer beads with an aminomethylpyridine, such as 2-picolylamine, N-methyl-2-picolylamine, N-(2-hydroxyethyl)-2-picolylamine, N-(2-methylaminoethyl)-2-picolylamine, or bis-(2-picolyl)amine. At a typical copper ore leach liquor pH of about 2, the picolylamine resins will absorb 15-30 mg copper/ml resin with a 5-10 fold selectivity for copper over ferric iron.

Abstract: Novel polycyclic macrocyclic compounds having four tertiary nitrogen bridgehead atoms and six bridging chains, each of which have not more than twelve directly connecting atoms between each pair of bridgehead nitrogens, said bridging chains being hydrocarbon chains and hetero-substituted hydrocarbon chains having at least one hetero connecting atom selected from the group consisting of oxygen, sulfur, and nitrogen, at least two of said chains being hetero substituted. When admixed with a compatible cation-donor compound, the polycyclic macrocyclic compounds form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing acid. The novel polycyclic macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.The polycyclic macrocyclic compounds are prepared by condensation reactions utilizing high dilution techniques, e.g. by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon di-carbonyl halide followed by reduction of the resulting lactam or, alternatively, by condensing a monocyclic macrocyclic having secondary nitrogen bridgeheads with a substituted hydrocarbon dihalide (or di-sulfonate).

Abstract: Metal ions may be scavenged from solution by means of a complexing agent comprising an inorganic substrate, such as a clay mineral, with covalent organic molecules, such as onium compounds, chemically bonded to the substrate, the covalent organic molecules containing free coordinating groups. The complexing agents are particularly useful in scavenging environmentally harmful metal ions such as mercury from industrial effluents.
