In simple terms, very strong copper extractants extract substantial amounts of copper at pH values less than 1.0, while moderate strength copper extractants are most useful above a pH of 1.6-1.8. Another class of extractant combines a salicylaldoxime with a ketoxime in an approximate 1/1 mole ratio.
