Flotation of oxide copper ore with sodium oleate from

2020-5-12  The flotation of oxide copper ore with sodium oleate was investigated to determine the optimum pH and dosages of chemical reagents. From the mineralogical analysis using X-ray diffraction, malachite was the major mineral and the gangue minerals were mostly silicates such as quartz and kaolinite. As a result this ore was characterized as oxide ...

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

2014-12-24  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
