Mehdilo Department of Mining and Metallurgical Eng.,Nevertheless, using NaOH as a pH regulator, the dosage of Na 2 S is decreased significantly but the flotation results are affected negatively. The recovery of Zn in the concentrate is more sensitive to the

FLOTATION OF ZINC OXIDE ORE USING CATIONIC AND

2012-10-4  tion is decreased and an optimal concentrate with 94% recovery and 43% Zn grade is obtained without any gangue depressant reagents. Keywords: flotation, smithsonite, collector, mixed collector, zinc Introduction Nowadays, new technologies to produce zinc metal from oxidized zinc

Effect of Water Composition on Flotation of Lead and

similar tendency, sea water dramatically decreased zinc content of the rougher concentrate. Figure 4 (a) Effect of water composition on lead and zinc content at rougher flotation.

Minerals Special Issue : Flotation Reagents

Zinc is mostly extracted from oxidized zinc and zinc sulfide minerals, and this process involves flotation as a key step. While it is easier to float the sulfide mineral, its consumption and depletion has led to an increased reliance on oxidized zinc minerals, including smithsonite.

THE INFLUENCE OF WATER QUALITY ON THE FLOTATION

The quest is to optimize the separation between the lead and zinc, with maximum recoveries and grades, and to limit the use of cyanide as depressant for the sphalerite during the galena flotation.

Zinc Sulfide Ore Flotation MC Machinery

On the other hand, using SH in real oleic acid flotation of zinc oxide ore the grade of CaO was decreased while the grade of zinc also fell steeply . Flotation Process Controls Outotec Manual operation: The point at which the site is operating on the site-specific grade-recovery curve will determine the flotation

Understanding the depression mechanism of sodium

2020-3-5  The principle of reverse flotation is that valuable minerals are sunk [4,5]. Due to these minerals similar soluble properties and structures, direct flotation is inefficient. Therefore, reverse flotation of carbonate gangue and depression of apatite has been practiced by predecessors [4,6]. Thus, the understanding of depression mechanism of

Flotation Behavior of Complex Sulfide Ores in the

In this study, chitosan polymer was tested as a potential selective green depressant of pyrite in the bulk flotation of galena (PbS) and chalcopyrite (CuFeS 2 ) from sphalerite (ZnS) and pyrite (FeS 2 ) using sodium isopropyl xanthate as a collector and 4-methyl-2-pentanol (MIBC) as a frother. Flotation tests were carried out in a D12-Denver flotation laboratory cell in the presence and

Influence of temperature on sulphide ore flotation

study was applied to the rougher regrind flotation circuit (DPR) since this is the flotation stage in which greater losses in sphalerite recovery are registered. In studies carried out in the company in order to characterize the problem, two phenomena were identified in the zinc fluctuation circuit in periods of decreased sphalerite recovery, these

ROLE OF STARCH AND METABISUPHITE ON PURE PYRITE

2011-8-19  Flotation recovery decreased from 43% to 4% at pH 10, and from 75% to 23.3% at pH 6.5 with 134 mg/dm3 metabisulphide addition. Decrease in recovery with metabisulphate was about 40% at pH 10 where pyrite flotation is already low due to high pH and about 50% decrease in recovery was obtained at pH 6.5. Test results

The effect of mode of occurrence of galena and sphalerite

2009-8-26  The flotation response of a Pb-Zn sulphide ore from the Rosh Pinah Mine (Namibia) was studied in the presence of inorganic depressants such as sodium cyanide and zinc sulphate. Poor flotation selectivity was observed in the rougher concentrate of the galena circuit despite the use of a large amount of sodium cyanide.

2020-10-13  In the mechanical flotation cells the feed can be introduced directly to the impeller zone from the side as in a Denver-style Sub A sub-aeration machine. A centrally located paddle-wheel type impeller generates a rotating pulp vortex which extends between two stationary elements: the sand-pipe located at the top of the cell, and the draft tube located at the bottom of the cell. The hydraulic

1 Froth Flotation Fundamental Principles

2009-8-27  1 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. The particles with attached air bubbles are then carried to the surface and
