Increasing fine copper recovery at the Ok Tedi ...

Abstract. This paper describes laboratory and plant based investigations on methods to increase fine copper recovery during flotation treatment of Ok Tedi porphyry sulphide ores. Currently the Ok Tedi concentrator treats a mixed porphyry/skarn ore blend, which is ground to a d 80 of 180 μm with flotation carried out using a dithiophosphate ...

Effect of Desliming on Flotation Response of Kansanshi ...

The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was ...
