ABSTRACT:
Novel modified and improved beta-diketones and their use in the extraction of copper from aqueous ammoniacal solutions containing copper values, resulting from commercial processes, including, but not limited to, leaching of copper containing ores, such as sulfidic ores, or concentrates resulting from flotation of such sulfidic ores. The novel diketones are those highly sterically hindered, which may be represented by the formula I or II: ##STR1## The preferred beta-diketones of Formula [II] are selected from the group consisting of neo-alkyl beta-diketones, such as, 1-phenyl-3-neoalkyl-1,3 propanedione in which the neoalkyl group is selected from neohexyl, neoheptyl, neooctyl, neononyl, or neodecyl.
