copper recovery plant ore flotation line

Development of copper recovery process from flotation ...

15-06-2018  The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION

The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the

Sulphidation Of Copper Oxide Ores For Flotation

The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation which was first developed with industrial success on PbZn oxide ores in Australia Croier 1991. The method involves multistage addition of sodium sulphide Na 2 S sodium hydrogen sulphide NaHS or ammonium sulphide NH 4 2.

01-11-2014  1. Introduction. Gold recovery is often well below copper recovery in copper–gold flotation plants (Zheng et al., 2010).As liberated and copper-associated gold is readily recovered by flotation, this recovery difference is often due to operating strategies that require rejection of gold-bearing iron sulphide gangue in order to maintain a saleable copper concentrate grade.
