Abstract

'Ενα ανάμικτο συμπύκνωμα αρσενοπυρίτη, σιδηροπυρίτη και πυρρωτίτη επεξεργάζεται πρώτα, κατά ένα στάδιο βιολογικής οξειδώσεως κατά το οποίο ο πυρρωτίτης και ένα μέρος του αρσενοπυρίτη οξειδώνονται, και κατόπιν κατά ένα στάδιο οξειδώσεως υπό πίεση, στο οποίο οξειδώνονται ο σιδηροπυρίτης και ο παραμένων πυρρωνίτης και ο αρσενοπυρίτης. Η μέ?οδος αυτή είναι ιδιαίτερα χρήσιμη για την επέκταση μιας υφιστάμενης εγκαταστάσεως οξειδώσεως υπό πίεση. ω A mixed concentrate of arsenopyrite, ferrosilicon and pyrrhotite is first processed, in a biological oxidation step in which the pyrrhotite and part of the arsenopyrite are oxidized, and then in a pressurized oxidation step, in which the oxidizer and oxidizer . This method is particularly useful for extending an existing pressure oxidation plant. ω
