Selective Flotation of Elemental Sulfur from Pressure

Figure 1. Appearance of the pressure acid leaching residue of zinc sulfide concentrate. 2.2. Experimental Methods The flotation experiments of pressure acid leaching residue were performed in a self-aeration XFD-63 flotation machine [26. 28]. At the beginning of the test, the residue and

Recovery of zinc and lead from Yahyali non-sulphide

Five flotation methods, help you processing lead-zinc

Aug 23, 2021 The sulfide-xanthate flotation method can be used to flotate lead minerals first, while sodium carbonate and sodium silicate are used to flotate gangue minerals, and fatty acid collectors are used to flotate zinc oxide minerals. Fatty acid collector flotation method is mainly used for flotation of lead-zinc oxide ore with low iron content and a

(PDF) Leaching of zinc from a lead-zinc flotation tailing

Ferric sulphate/sulfuric acid leaching of zinc from a Pb-Zn flotation tailing sample was investigated in detail. 0.5 mol L -1 ferric sulphate was found to be enough to dissolve both oxidized and

Selective Flotation of Elemental Sulfur from Pressure Acid

An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. The process mineralogy analysis showed that the sulfur content reached 46.21%, and 81.97% of the sulfur existed as elemental sulfur which was the major mineral in the residue and primarily existed as pellet aggregate and biconical

How to Process Low-Grade Lead Zinc Ore by Flotation

Apr 27, 2016 The zinc tailings pass over a Wilfley Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener

Flotation Reagents - Mineral Processing & Metallurgy

Flotation Behavior of Iranian Oxidized Zinc Ore Using

Apr 01, 2015 In this study, the flotation of oxidized zinc ore from Angooran ore in the presence of cationic collector such as dodecylamine (DDA), anionic collectors such as oleic acid (OA), potassium amyl xanthate (KAX), hexyl mercaptan (HM) and mixed collector (cationic/anionic) was investigated. The parameters of the flotation process such as recovery, grade and the effect of using some collectors

Selective Acid Leaching of Copper and Zinc from Old

The goal of the present work was to develop hydrometallurgical method based on acid leaching, which makes it possible to perform selective extraction of non-ferrous metals from old flotation tailings. Leaching was performed with sulfuric acid solutions (from 0.5 to 10%) and distilled water. Leaching was carried out using percolators and bottle agitator

Leaching of Zinc from Calcined Angouran Plant Flotation

The aim of this study was to investigate the possibility of leaching zinc from the tailing (-2 mm) of Angouran flotation plant using sulphuric acid. The tails were first calcined at 800C for one hour. The effect of factors such as stirring rate, temperature, initial acid concentration and solid/liquid ratio, on zinc extraction were studied. The results obtained show that at the best conditions

Testing of 17-different leaching agents for the recovery

Jul 01, 2021 Reference, where oxalic acid has been used to dissolve the zinc from the flotation tailing (Kursunoglu et al., 2021), have been excluded from the current paper as the oxalic acid has extracted a substantial amount of iron together with zinc from the flotation tailing. 2
