Ion flotation is an efficient separation technique for the recovery of metal ions from dilute aqueous solutions. Provided that both the collected metal and the surfactant are recovered from the phase, it could be considered as an alternative to ion exchange, adsorption or solvent extraction in hydrometallurgy. However, most studies …
Two flotation tests were conducted to duplicate the experiment. Zinc sulfate (ZnSO 4) and dextrin (Dextrin Gul) were used in the copper-lead rougher flotation stage to depress sphalerite whereas potassium amyl xanthate (KAX) and triethylene glycol monobutyl ether (Nasfroth 240) were used as a collector and frother reagent, …
This group of frothers is widely used in the flotation of zinc, lead and copper minerals significantly improving the flotation efficiency (Numprasanthai et al., 2013, Tsatouhas et al., 2006). The last category are polyglycol-based polymers. They can be divided into two groups: polyglycols and polyglycol ethers (Bulatovic, 2007).

What are the flotation processes of common minerals (copper ore, lead-zinc ore, iron ore, etc.)? The flotation of different minerals with different properties in industrial production requires different prescriptions and flotation processes. Flotation of copper There are many methods for beneficiation of copper ore.
Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a …
Pulp concentration has varying degrees of influence on reagent consumption, pulp aeration and flotation machine production efficiency, thus affecting mineral flotation efficiency. Within a certain range, as the concentration of the ore pulp increases, the minerals and chemicals become more likely to collide and contact, and the minerals float ...
The pH values of 6 and 8 were selected as optimum pH for the lead and zinc flotation respectively. Lead, zinc, and iron flotation kinetic rates in the lead flotation stage at pH values of 6 and 8 were shown in Fig. 10. As it can be seen, there is a sharp increase in the lead recovery in the first minute and then the lead recovery gradually ...
Under these conditions, copper-bearing iron powders (CIP) with an iron content of 90.11% and copper content of 0.86%, indicating iron and copper recoveries of 87.25% and 83.44% respectively, were ...
The ways to obtain successful Separation of Copper and Lead into individual Concentrates, several process approaches can be examined; bulk copper-lead flotation with a reverse flotation stage depressing copper, the same bulk flotation with a reverse flotation to depress lead and a sequential copper-lead-zinc flotation circuit as well as …
The purpose of this study is to identify the physical, mineralogical, and electrochemical properties of copper flotation tailings as well as to investigate how …
Abstract. Collector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type …
Strategic blending offers a method to consistently achieve the desired feed grade, enhancing copper flotation performances. Blending different ores can balance the …
The commonest depressing reagents are lime, sodium cyanide, and zinc sulphate. Lime is extensively used to prevent pyrite from entering the concentrate of other minerals particularly copper and zinc sulphides. Its action is positive and progressive ; it is only necessary to add it to the pulp in sufficient quantity to make the pyrite unfloatable.
Dolomite Mining Process. Dolomite mining process is the solution of separating dolomite concentrate from Dolomite raw ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences, Xinhai applying Dolomite mining process of two-stage crushing, washing, then three-stage separating, flotation process will be used to …
This paper aims to discuss the concepts of an integrated plant optimization tool for the flotation of copper and copper–gold ores using Ore2Metal's FLOT-ART …
In the rougher flotation stage, a lead concentrate with 17.29% Pb and a zinc concentrate with 9.89% Zn could be obtained by 76.71% lead and 15.49% zinc …
The possibility of selective Cu and Zn leaching from the sample of old pyrite tailings, which is one of the most widespread types of solid waste forming during non-ferrous metal production, using sulfuric acid solutions and water was studied. It was shown that water leaching provided selective extraction of Cu and Zn and comparatively low …
Copper is most commonly present in the earth's crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).
