evident that the major challenge in the flotation of these ore bodies is the control of the gangue minerals, both the silicates and the chromitite. This paper presents results obtained in an extensive programme of testwork investigating the influence of various factors on the behaviour and control of the gangue minerals during flotation.
Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold. For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

2.5 The use of depressants and clay binders In flotation, sodium silicate (Na 2SiO 3), called water glass, has fairly common use to depress silicate and carbonate minerals present as gangue minerals. Also, it is an effective dispersant.

A transformation matrix model that explicitly incorporates mineral liberation has also been developed to quantify the influence of mineral liberation on flotation performance. Related items Showing items related by title, author, creator and subject.
flotation process 1 . In order to obtain a successful flotation of slimy sulphide ores, two types of chemical auxilliaries are basically in use i. e. ( i ) a hydrocolloid acting as flocculent for gangue material, commonly referred as a depressor and (ii) a collector or a metal reagent, which condit-ions the mineral surface ( by adsorption and
Flotation Process In Mining Fotation Machine Ball Mill . Flotation is a mineral separation process done in the water medium It is based on the difference in the surface properties of the mineral and gangue The surface of the selected mineral is made hydrophobic water repellent by the use of selective reagents and these particles get attached to the air bubbles that are introduced in the system
In flotation concentration, the mineral is usually transferred to the froth leaving the gangue in the tailing in direct flotation and in the reverse flotation the gangue is separated into the float action leaving the concentrate in the pulp. In flotation, the minerals can be classified as hydrophobic, i.e., having no affinity towards water and
• evaluation of mineral and water chemistry which can affect the flotation process; and (coarser or finer), reagent system and flotation times to further enhance mineral recovery. Should recovery problems persist then a detailed mineralogical examination is separation of value minerals from gangue) may not benefit significantly from
Coal gangue identification flowchart. Technical features ※ Wide processing size range: It can handle 30- 600mm raw coal. The upper limit of separation is 600mm and the lower limit is 30mm. ※ High separation accuracy: The rate of gangue removing is over 95%, the rate of coal in gangue is less than 2%, and the separation effect is significant.
Slurry Treatment and Flotation Reagent Selection of Non-sulphide Mineral Flotation. Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in
In the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from waste rock (gangue); it is conditioned as a slurry using specific chemicals, generically referred to as 'collectors', that adsorb to the surfaces of the desired minerals.
Early work in the flotation group focused on a wide range of problems associated with these flotation plants. Subsequently the focus widened to include research on: platinum group minerals of which South Africa is the world's leading producer; the depression of gangue minerals
These are called gangue minerals. An ore deposit rich enough to work with profits is called an ore deposit and is called ore minerals plus gangue ore in an ore deposit. Vein-Mineral-Deposits. Note. Ore deposits are an economic term and the beds are a geological term. gravity separation and flotation. Second is melting, it releases the

upgraded to 90% in grade by froth flotation and the sulfur concentration can be followed y sulfur purification and selenium and tellurium removal. The sulfur inb the leaching is in a form of discrete particles with a size range of 5 to 10 microns. The sulfur particles tend to agglomerate in the pulp and hence mechanically entrap gangue minerals.
separate from the gangue by conventional flotation techniques. In the case of oxide zinc ores, there is often no selectivity in terms of zinc recovery. The objective of the present study is to investigate the influence of different cationic, anionic and mixed collectors on the flotation of smithsonite mineral and an oxide zinc ore at various
tration, at which sulphide metal minerals are separ-ated from gangue minerals. In this step, two main pro-ducts are produced – concentrate as a feeding mat-erial for smelters and flotation tailings as a waste, which is discarded in flotation tailings ponds. It is an axiomatic approach that qualitative

dispersant widely used in iron ore flotation for silicate gangue minerals, is inadequate to disperse kaolinite[35]. A low molecular weight polyacrylic acid was found to induce full dispersion of kaolinite particles, in the presence of calcium and magnesium ions in alkaline pulp[34]. In addition to kaolinite, gibbsite, of general chemical

Therefore, adding targeted inhibitors of gangue mineral during flotation can increase the recovery rate of oxidized zinc ore. A large number of experiments have shown that hexametaphosphate can effectively inhibit quartz and dolomite gangue; water glass has the best inhibitory effect on sericite, chlorite and iron gangue; sodium humate has a

Flotation is used to separate sulfide ores from the impurities in the ore . A detergent is added to the mixture and it is stirred. The sulfide minerals float, while the gangue sinks to the bottom and is removed. This is used in making zinc, where zinc sulfide is a major zinc ore.
If there are weak boundaries between mineral and gangue then there will be high degree of liberation; If adhesion is strong then this produces much middlings and low degree of liberation; To increase the degree of liberation involves directing the breaking stresses at the mineral crystal boundaries
