Pyrite Flotation Zinc - Nasobchudek.cz
Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

Study On The Pre-treatment Of Oxidized Zinc Ore Prior
The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.
The Adsorption Of Cu Species Onto Pyrite Surface And
The adsorption of Cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, first-principle calculations, and XPS surface analysis. The results indicated that the flotation of pyrite appears to be activated with CuSO 4 only at alkaline pH, while being depressed at acidic and neutral pH.
Role Of Starch And Metabisuphite On Pure Pyrite
2011-8-19Role of starch and metabisulphite on pure pyrite and pyritic copper ore flotation 43 occurred with 1.7 mg dm3, while 21 depression occurred with the same dosages of starch at pH 6.5 where pyrite flotation is expected to be weak at pH 10.
Copper-lead-zinc Ores - Danafloat
As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends.

Flotation Of Sphalerite And Pyrite In The Presence Of ...
2016-11-28Pyrite is one of the major diluents of copper, lead and zinc concentrates. One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc circuit to activate the flotation of sphalerite Bushell and Krauss, 1962 ...
Thermomechanical Aspect Of Selective
2016-1-10which mutilates flotation process. It is known that zinc cycle of copperzinc ore flotation uses xanthate modifications that are not selective relative to pyrite. In view of the aforesaid, it is re-quired to design a process flow chart toward higher efficiency of separation of zinc minerals and pyrite in the zinc cycle of flo-tation.
Dispersion Effect On A Leadzinc Sulphide Ore Flotation ...
This investigation was performed with samples from a leadzinc sulphide deposit aiming at studying the influence of the dispersion degree of the particles in the pulp on lead and zinc flotation. Samples of ore and also of the minerals sphalerite, galena, pyrite, and dolomite were selected for the experiments. Nine types of dispersing agents and six blends among them were employed. A set of ...

Depression Of Pyrite In The Flotation Of Copper Ores -
Pyrite flotation could also be reduced with addition of xanthate during grinding. In this case, the selective depression of pyrite flotation was attributed to the immobilisation of copper by xanthate at the chalcopyrite surface or its removal from solution, both mechanisms resulting in a reduced copper activation of pyrite.
