Sphalerite is sulphide ore, it is concentrated by froth flotation and then subjected to roasting to convert the sulphide ore to oxide ore. The oxide ore is reduced to zinc using carbon monoxide or ...

The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining ...

FloeFlotation of Chalcopyrite from a Low Grade Cu —Zn Ore fines (Song, S. et al, 2000, Song, S. et al, 2001). In the present study attempt has been made to explore the possibility of exploiting flocflotation to the flotation of chalcopyrite fines from a low grade ore using simple, conventional collectors and kerosene (Shende et al. 2005).

Copper ore is the main mineral for the large deposits. Copper minerals are mostly consisting of chalcopyrite, secondly consisting of bornite, there are traces of processing copper blue and malachite, the mineral is disseminated by coarse granularity. This mineral is easy to processing. Production process was using by the process of grindingflotation.

of copper sulphate dosage that can activate the chromite and also to evaluate the effect of the depressant type and dosage on the recovery of chromite in the flotation of UG2 ore. The two depressants selected were for evaluation of the guar gum, IMP4 and the carboxymethylcellulose (CMC), KU5. Flotation performance was evaluated using the ...

ABSTRACTThe effect of chemical reagent configurations was investigated on two different copper sulphide ore types, including high and low pyritic feeds. ... and sodium isopropyl xanthate (Z11) were used in flotation experiments. Solely using C4132 was selected as the best pattern for both feed types with regard to achieving the highest copper ...

Flotation of a copper sulphide ore from Okiep using thiol . Flotation of a copper sulphide ore from Okiep using thiol collectors and their mixtures by G. Hangone*, D. Bradshaw, and Z. Ekmekci Paper written on project work carried out in partial fulfilment of MSc thesis Synopsis This paper investigates the effects of thiol collectors xanthates

We study the effect of one of the main parameters of flotation oredressing, specifically, alkalinity of the pulp, on the selective flotation of sulfide and oxide minerals of copper from the Udokan deposition ores (Chita oblast). It is found that the optimum values are pH = 9 for sulfide minerals of copper and pH = 10 for the oxide ones.

flotation time. After the optimum conditions were determined, finally flotation experiment was carried out using 16 kg ore sample. The flotation test was conducted in a 10 dm3 flotation machine at an impeller speed of 2200 rpm for each test of 4 kg. Rougher molybdenum concentrates obtained from each test of 4 kg were combined
