Question
The practical application in the froth floatation process for the concentration of ores is:
- Adsorption
- Absorption
- Evaporation
- Decantation
Hint:
concentration of ore
The correct answer is: Adsorption
Froth flotation process for the concentration of ore is an illustration of the practical application of Adsorption. In this process, the sulphide ore gets preferentially adsorbed over the impurities while that of ore particle by oil. A rotating paddle agitates the mixture and draws air in it.
