1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while ...

Law of Flotation. Difference between Floating and Sinking of Objects. As we have discussed in upthrust, different objects with different density can sink or float. The object with higher density than water density will sink while that object with a density lower than water's density will float. For example, a coin sinks in water and a large ...

When a body floats with its volume partially above the liquid surface, the volume of the liquid displaced by the body is equal to the volume of submerged portion of the body. Since the body is in equilibrium, the force of buoyancy acting on the body must be equal to its weight. This is known as the law of floatation.
