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

Chalcopyrite and pyrite floatabilities in the presence of
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

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.

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

Copper processing Ores Britannica
Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Improving the efficiency of oxide copper–cobalt ores
Abstract Sulphidising flotation of oxide copper–cobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga, Democratic Republic of Congo. From laboratory investigations, sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals, while ammonium sulphide emerged as a strong non-selective sulphidiser.
