✦ Synopsis

The use of substituted oximcs as commercial reagents for the separation of copper from leach liquors was first introduced by Gcncral Mills Inc. in 1963, the first rcagcnt being LIX-63'. Since that time, two more reagents of a similar nature have bccomc available".", LIX-64 and LIX-64N. The latter are more stable towards acids and more sclcctivc for copper than is LIX-63. The general structure of these reagents is given as' YH Y-OH R-C -C-R' R,,
