Froth Floatation This method employs a mixture of water and pine oil which is made to froth in a tank to separate sulphide ores. The differences in the wetting properties of the ore and gangue particles separate them. A mixture of water, pine oil, detergent and 1985/4/30Froth flotation was then carried out for 3 minutes, after which time the concentrate was dried, weighed and ashed. Flotation test results for this example, its control and comparative examples 7-A (sodium sulfite depressant) and 7-B (sodium salt of the

Zinc blende is concentrated by floath floatation process. The pulverized ore is kept in large tank containing water and pine oil. The mixture is agitated by passing compressed air. Ore forms froth and comes to the surface while impurities are left in water.

2010/2/20froth floatation procees is for purification of ores it is mainly used for sulphide . first powdered ore is taken in beaker with water and pine oil which is foaming agent . then compreesed air is passed then the ore come to surface as foam while impurities are settle at bottom of beaker.

Which of the following statements is correct about the role of substances addedd in the froth floatation process? 6.7k LIKES 3.5k VIEWS 3.5k SHARES Text Solution Collectros enhance the non-wettability of the mineral particles By using

Hydrophobicity of mineral particles is the most important characteristic in the froth flotation process. It gives an opportunity to a particle to get attached to air bubbles during collision. It can be called true flotation but on the other hand some undesired particles (irrespective of hydrophobicity) might attach to the bubbles and enter into the froth zone, which is called entrainment.

2018/6/1Sulfidation is an important process in oxidized ore flotation. In this study, the influence of sulfur ion adsorption on smithsonite surface was investigated with the use of zeta potential, inductively coupled plasma (ICP), scanning electron microscope (SEM),

Froth Floatation Process In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method. In this method advantage is taken of the referential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or terpentine oil .

In the froth flotation process gangue particles are separated from the values (often mineral ores or coal) by virtue of differences in hydrophobicity; the more hydrophilic gangue resides in the interstitial liquid where it drains downwards whereas the more hydrophobic values rise with the bubbles into the concentrate stream.

Froth floatation process is used for the concentration

Jul 29,2020 - Froth floatation process is used for the concentration ofa)Chloride oresb)Oxide oresc)Sulphide oresd)AmalgamsCorrect answer is option 'C'. Can you explain this answer? | EduRev NEET Question is disucussed on EduRev Study Group by 182 NEET

A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth. This happens because NaCN reacts with

In froth floatation process sulphide ore is shaken with pine oil and water, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank.Thus, role of adsorption in froth floatation process can be understood as following processes. (i

Froth Floatation Process which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth. The gangue particles being heavier remain behind at the bottom of water tank. The froth is separated and concentrated sulphide ore is
