ABSTRACT:
Metal values, especially copper values, are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by a 1,2,4 triazole substitued in the 1- position by (1) a hydrocarbyl (alkyl) group or (2) a group of the formula --(X).sub.n --(CO--Y).sub.m where X is an optionally substituted methylene, vinylene or phenylene linking group or a linking group of formula --CO--A-- where A is an optionally substituted aromatic ortho linking group; n is 0 or 1; Y is OR.sub.2 or R.sub.3 where R.sub.2 and R.sub.3 are hydrocarbyl groups containing from 5 to 36 carbon atoms (preferably branched alkyl groups containing from 9 to 24 carbon atoms); and m is from 1 to 3.
