Solution
Physical Property That Flotation Relies On
Flotation is a separation process that relies primarily on density. The basic principle of flotation is that materials with different densities will behave differently when subjected to a liquid medium.
-
Density: This is the key physical property for flotation. Materials with lower density than the liquid will float, while those with higher density will sink. The differences in densities allow for the separation of useful minerals from unwanted material.
-
Particle Size: While particle size can influence the efficiency of flotation, it is not the primary property that the process relies on.
-
Solubility: This property is related to how well a substance can dissolve in a solvent, but flotation operates more on the physical separation of phases based on density differences than on solubility.
-
Boiling Point: This property pertains to the temperature at which a substance transitions from a liquid to a gas, and it does not play a direct role in the flotation process.
In summary, the flotation process mainly depends on the density of particles to achieve separation effectively.
