Abstract
1. Process for removing selectively iron from acidic chlorous solutions originating in leaching complex sulfide ores to produce non-iron metals comprising oxidizing the ferrous iron present in said solution to ferric iron by introduction of an oxidizing gas into said solution and subsequent filtering and washing the so formed precipitate of ferric iron, characterized in that the starting solution has a concentration of copper [Cu**++ ] =< 1,5 M and a concentration of ferrous iron [Fe**++ ] =< 2 M and that one introduces said oxidizing gas into said solution with a constant throughput during at least the first half of the duration of the reaction and one increases continuously the partial pressure of the oxygen in said gas in function of the time to maintain the velocity of the oxidation reaction constant during at least the first half of the duration of said reaction.
