Abstract
This paper presents a part of the results from flotation concentration examination of pure chalcopyrite mineral from the deposit of the mine Rudnik in the frothless cell. The examinations were performed in seven series. In the first three series, the conditions under which the recovery of chalcopyrite from the Rudnik mine has the highest value were determined. The examinations was performed as a function of collector (KAX) consumption and pH. In the fourth and fifth series, the possibility of chalcopyrite depression as a function of depressant (NaCN) consumption, collector (KAX) consumption and pH was investigated. In the sixth and seventh series, the possibility of activating previously depressed chalcopyrite as a function of collector (KAX) consumption and pH was investigated.
