احصل على السعرSulfate based leaching processes for chalcopyrite (CuFeSa) are attractive because of their inherent simplicity. Unfortunately, high copper extractions are not attainable in a reasonable residence time unless the leaching temperature exceeds 200°C (oxygen pressure leaching) or chalcopyrite is "activated" by a pretreatment method prior to leaching. In the present work, the oxygen pressure
