摘要： A composition of bibenzimidazoles of the Formula (I): ##STR1## wherein X & Y which may be the same or different and, taken together, contain a total of from 12 to 52 saturated carbon atoms, are (a) each selected from --R, --COR, --CH.sub.2 COOR, --CH(COOR).sub.2 and --COOR; or (b) together form a group selected from ##STR2## wherein R is an optionally substituted hydrocarbyl group,A & B taken together with the two carbon atoms to which they are linked form an optionally substituted benzene ring; andC & D taken together with the two carbon atoms to which they are linked form an optionally substituted benzene ring;characterised in that at least 50% by weight of the bibenzimidazoles in the composition are of Formula (II) ##STR3## wherein X and Y are as hereinbefore defined;T, U, V & W which may be the same or different, are H, R.sup.1 or OR.sup.1 provided at least one of T, U, V & W is R.sup.1 or OR.sup.1 ;and R.sup.1 is C.sub.1-6 -alkyl;which are suitable for use in the extraction of zinc from aqueous solutions of zinc in the presence of other metals.

摘要： Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyridine derivatives containing the substituent --(COX).sub.A where X is the group --OR.sub.1 or --NR.sub.2 R.sub.3 and n is 1, 2 or 3. R.sub.1 is a hydrocarbyl group containing from 5 to 36 carbon atoms and R.sub.2 and R.sub.3 are hydrogen or a hydrocarbyl group wherein R.sub.2 and R.sub.3 together contain from 5 to 36 carbon atoms. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containing ores such as chalcopyrite.
