May 07, 2007· ABSTRACTOne of the principal problems in flotation of copper complex ores is the presence of pyrite and copper-activated pyrite in moderately alkaline pHs. Misreported pyrite into copper concentrates dramatically declines copper grade and its recovery. In this study, the effect of sodium sulfide, sodium metabisulfite (SMBS), and their dosages (100, 200, 300, and 400 g/t) were

Review, Evolution and Optimization of the Kansanshi Mixed

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

Separation efficiency improvement of a low grade copper

Ore is processed through both trains in a variety of configurations. The predominant configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with cyanide to recover gold.

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

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

Jul 08, 2011· 1. Introduction. Wet milling in ball mills followed by flotation is the general practice employed in the beneficiation of copper sulphide ores in which the major minerals of commercial significance typically are chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S). The flotation response of ground minerals can be influenced by the grinding conditions used

A New Application For Flotation Of Oxidized Copper Ore

In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.

The Effect of Oxidation on the Flotation Behaviour of

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.
