ABSTRACT:
A process is disclosed for recovery of cobalt and manganese, and other metals, in the form of their acetate salts, directly from mixed metal oxides present in oxidation residue incinerator ash comprising fly ash and clinkers from incineration of a residue from manufacture of benzene di- and tricarboxylic acids by catalytic means. These acetate salts are recycled directly for manufacture of benzene di- and tricarboxylic acids after recovery.
