Two sulphide ores can be separated by adjusting the proportion of oil and water or by using depressants, e.g., if an ore contains ZnS and PbS both, a depressant NaCN is added during froth floatation. It forms a complex with ZnS and prevents it from coming into froth. PbS comes into …
Main floatation agent is sodium ethyl xenthate. The name of collector is Pine oil, Sodium ethyl Xanthate and the name of froth stabilizeris aniline,Cresol. In froth flotation process, the role of collector (Pine oil, Sodium ethyl xanthate) is it attracts the ore particle on the surface of the froth.This mechanism takes place by surface adsorption.

The process of froth flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate. In this method of mineral processing, the ores contain multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation.

froth is generated by blowing air through this mixture. The collector molecules attach to the ore particle and make them water repellent. As a result, ore particles, wetted by the oil, rise to the surface along with the froth. The froth is skimmed off and dried to recover the concentrated ore. The gangue particles that are preferentially
Important Topics Chemistry: 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. A strong current of air is blown through the suspension ...
As a result, is formed which carries metal sulphide particles. The rises to the surface of water and floats. Therefore, this method is called froth floatation process. This method is used to separate metal sulphide ores such as zinc blende (ZnS) and copper pyrite (CuFeS 2). Froth floatation method

2. Describe with labelled diagram, the Froth Floatation Process used to separate the gangue from a Sulphide ore. Ans: Sulphide ore is mixed with water and pine oil. The mixture is agitated (shaken vigorously) with the help of stirrer in the blast of air.
The steps involved in the extraction of zinc from zinc blende (ZnS) are as followed:-. 1) Concentration: the ore is crushed and then concentrated by froth floatation process. 2) Roasting: the concentrated ore is heated in the presence of an excess of air at about 1200K …
Write a short note on froth floatation process. Froth floatation process is used for concentration of sulphide ores mainly. The particles based on differences in the ability air bubbles that selectively attach to specific mineral surfaces in mineral water slurry are separated by this method. In this method, crushed ore is suspended in water and ...

Which ores are concentrated by froth floatation process. Write in brief description and draw labelled diagram. Answer: This process is generally used for the concentration of sulphide ores. For example: Copper pyrite (CuFeS 2], Galena [PbS], Zinc Blende (Zn) etc. Method: Water is taken in a big rectangular utensil.
(A) Solid state (B) Fused state (C) Gaseous state (D) Do not conduct electricity at all. 6. Which of the following methods is based on the principle of the difference in the wetting properties of the ore and gangue particles with water and oil ?

Depressants prevent certain type of particles from forming froth during froth floatation process. 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.
