Abstract

Metallocomplex anions may be recovered from aqueous cyanide liquors by contacting the liquor with a low capacity strong base resin which comprises a fully halomethylated cross-linked aromatic polymer in which 10-60% of the halomethyl groups have been reacted with one or more tertiary alkylamines in which the alkyl groups, which may be the same or different, each contain from 4 to 7 carbon atoms, which alkyl groups are linear or branched, provided that the branching does not occur at the first carbon atom. After contacting the anions may be eluted. Metallocomplex ions which may be present contain gold or silver. Specifications 727,582 and 947,631 are referred to.ALSO:A process is described for producing a low-capacity strong base anion-exchange resin which comprises fully halo-methylating a cross-linked aromatic polymer and then reacting with a tertiary alkylamine in which the alkyl groups may be the same or different and contain from 4-7 carbon atoms in a straight or branched chain provided that the branching does not take place at the first carbon atom. The polymer can be polystyrene cross-linked with 1.5 - 10% of divinyl benzene or other material. Halomethyltion is carried out by treating with chloromethyl ether in the presence of stannic chloride. The amination is carried out by treating with the tertiary amine (tri -n -butylamine and tri - n - amylamine specified) preferable in the presence of an inert swelling agent (such as dioxan or chlorobenzene) and heating under reflux until 10-60% of the halogen present has been reacted. The resin preferentially absorbs gold and silver from aqueous cyanide liquors. Specifications 727,582 and 947,631 are referred to.
