A study of the effect of grinding environment on the flotation of
In the present study, the effect of various grinding conditions such as wet or dry grinding and addition of lime to the mill compared to the flotation cell on the The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high temperatures.A study of the effect of grinding environment on the flotation of

Copper recovery from copper slags through flotation
The ores are concentrated through froth flotation in the form of copper-sulfide or copper-iron-sulfide minerals (e.g. chalcopyrite, chalcocite and etc.), which are then melted in a high-temperature reheating furnace (± 1250 ℃). Under oxidation conditions, copper tends to form metallic copper and copper oxide [13].A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial.

Mineralogy and Innovative Flash Flotation Separation of Cu-Pb
Pyrite in complex metallic ore is a widely distributed sulfide on earth, commonly associated with copper, lead, and zinc sulfides, as well as gold and silver [1,2].The production of separate concentrates from ores containing economic amounts of copper, lead, and zinc is complicated [], especially for ores with high pyrite content Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate anything from 2 percent down to 1 percent or even 0.8 percent of copper. Thus to obtain metallic copper, up to 99 percent of the material mined must be removed 60 Centuries of Copper: The Flotation Process

The recovery of copper, by flotation, from calcium-ferrite-based
The copper was present in the form of metallic copper, oxide copper and copper ferrite phases with the dominant phase in all slags being metallic copper. The slags were crushed, ground, wet screened at 210 or 75 μm to remove coarse metallic particles of copper, and floated at natural pH (about pH 11) using reagents and conditions Electrochemical control of metallic copper and chalcopyrite-xanthate flotation.

Flotation of gold and gold-bearing ores ScienceDirect
1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937; Rabone, It was found that controlled pulp potential (Eh) flotation is a prospective approach to promote the separation of arsenic-copper minerals from other copper sulphides due to the strong Eh dependence of arsenic minerals flotation (Menacho et al., 1993; Yen and Tajadod, 2000; Kantar, 2002; Guo and Yen, 2005; Senior et al., 2006; The flotation of metallic arsenic as a function of pH and pulp

Slags are a left-over of the pyrometallurgical stages of recovery of non-ferrous metals from sulfide materials. Production of 1 t of copper results on average in formation of 2.2 t of slag; the annual global output of copper-smelting slags is ~ 25 Mt (Gorai et al., 2003).Due to the absence of an accepted efficient technology for extraction Leaching of copper and zinc from copper converter slag flotation

The Recovery of Copper from Smelting Slag by Flotation Process
Flotation Results. Figure 2 shows the effect of grinding fineness on recovery rate of copper. It is observed that a rise of the proportion of the grinding fineness of −0.074 mm from 60 to 80% obviously increased the copper recovery,then decreased when it exceeded 80%. This is because the initial appearance was dissociation fragmentationSulfide copper mineral, typically Chalcopyrite (CuFeS<sub>2</sub>), is one of the most common minerals for producing metallic copper via the pyrometallurgical process.

UTILIZATION OF FLOTATION IN COPPER EXTRACTION FROM
Natural copper is rare and represents about 1 % of all copper compounds. Copper may be present either in the form of sulphide ores, forming 90 % of copper compounds, or 9 % as oxidic ores [7]. The typical contents of copper in sulphide ores is 0.6 %, particularly primary sulphides (e.g. chalcopyrite and bornite) or secondaryIntroduction. 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).
