The concentrate products of copper, lead, and zinc can be obtained via flotation separation. The concentrate products of sulfur can be obtained only when the ore's pyrite content is high. Gold and silver can be recovered from the concentrates of copper, lead, and zinc or from the products of pyrite.
Question 2. Answer. In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.
The recovery of copper from copper smelter slag utilizing flotation has been studied. A copper smelter slag from the Wang Jiaqiao smelter in Yunnan Province of china, containing % Cu, % Fe, % Zn and /t Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined.
HISTóRICO. The Staged Flotation Reactor (SFR) was developed by going back to the first principles of flotation and examining how best to optimize the various phases of flotation without preconceived constraints. The result is a machine that optimizes the three stages of flotation within three separate zones, such that each zone is mutually exclusive...
ABSTRACT 484 Characterizing flotation recovery variability of copper ores Cornelius F Vos* Deirdre J Bradshaw Julius Kruttschnitt Mineral Research Centre, Sustainable Minerals Institute, University of Queensland, Brisbane, Australia ABSTRACT The detailed understanding of the variability in process performance parameters within an ore body forms a key aspect of ensuring that proper decisions are .
Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
copper principle ball mills; copper principle ball mills. Difference Between Sag Mill vs Ball Mill mech4study. Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting.
Flotation copper sulfide nickel ore, often used in the flotation of copper sulphide minerals collector and frother. A basic principle for determining the flotation process, would prefer to make the copper into the nickel concentrate, as much as possible to avoid nickel into copper concentrate.
The adsorption was relatively weak, and more copper ions in solution precipitated the collector and depressed the flotation of pyrite. XPS analysis confirmed that more copper ionic species (Cu(I) and Cu(II)) are adsorbed on the pyrite surface at alkaline pH than that at acidic and neutral pH.
To understand the basic principles of copper extraction from ores . of copper and have to be concentrated before refining (, via froth flotation). Figure 1: .. The anode sludge will contain valuable metals such as silver and gold. .

Sep 18, 2019· Froth flotation is one process for separating minerals from the surrounding worthless material by taking advantage of differences in their hydrophobicity. whereby hydrophobicity differences between valuable minerals other material are increased through the use of surfactants and wetting agents (Figure (PageIndex{3})). Flotation is used for the separation of a large range of sulfides, .
Dec 18, 2015· Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries.
Among the flotation reagents, commonly used activators for flotation are sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate and so on. Inhibitors: It is a kind of reagents mainly used to increase the hydrophilicity of minerals and to form a hydrophilic film on the .
