With this process, copper was recovered first with MBS depression of lead, zinc and pyrite. Lead was recovered after conditioning, utilizing cyanide as the base depression scheme to control sphalerite and pyrite. In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal.
A unique technology of direct selective flotation is in use in flotation plant of the & 34;Rudnik& 34; mine in order to obtain selective lead, copper and zinc concentrates.
The copper, lead and zinc concentrators in Taolin, Huanren, Tianbaoshan, Hesan, Zhanggongling, Bajiazi, etc. adopt this kind of process. Flotation process with equal floatability. According to the flotability of minerals in ores, the flotation flotation of good, medium and poor mineral groups is successively carried out, and then the mixed concentrates are separated into different useful ...
The copper-lead-zinc ores have an origin similar to copper-zinc and lead-zinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals. In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickel.
The Qixia orebody is a complex lead–zinc sulfide system with pyrite gangue and minor amounts of copper. In order to improve the flotation results, laboratory scale flotation testing of ore ...
Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in ...
In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals. Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails.
13.1 SOME GEOLOGICAL AND MINERALOGICAL FEATURES OF COPPER-ZINC ORES RELEVANT TO FLOTATION The geology and mineralogy of copper-zinc ores is similar to that of copper-lead-zinc ores, and in most cases, these ores are grouped together with copper-lead-zinc ores.
If the talc levels are sufficiently high and negatively impact metallurgy, talc depressants can be used in both the copper and zinc flotation circuits. These depressants include carboxymethyl, cellulose, dextrin, guar gum, and starch. Talc flotation interference can
AEROPHINE , AERO and AEROFLOAT collectors promoters are used extensively for the flotation of sulfide minerals including copper, gold, lead, zinc, nickel, iron and many others, such as lithium. These products provide improved performance and higher selectivity than more traditional sulfide collectors and better overall metallurgical ...
Then, if present, the zinc sulfide is floated, followed by the flotation of lead minerals. Either sodium sulfide or sodium hydrosulfide is used as a sulfidizing agent Önal et al., 2004 .
Sulphide ores are the major sources of base metals like Copper, Lead, Zinc, Nickel and Cobalt. Beneficiation of these base metal sulphide minerals is predominantl y through the froth flotation ...
Abstract: Froth flotation of copper-zinc-lead ores is a complex process based on similar metallurgy processing and strong interactions between chalcopyrite and sphalerite. These types of ores represent 15% of the world production and 7.5% of copper deposits all over the world. In the present study, an attempt is
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process this article was most recently revised and updated by chelsey parrottsheffer, research editor

A novel flotation promoter used in the concentration of copper bearing ores for the efficient selective flotation of copper values, including chalcopyrite, with suppression of iron pyrites; the promoter comprising a sodium sulfate of an aliphatic hydrocarbon having a carbon chain in excess of 12 carbons and chemically combined with at least one mole of the C 2--C 3 alkylene oxides.
This data on chemicals, and mixtures of chemicals in froth flotation with some of the more common flotation reagents and their uses.
