Principle of Floatation - Archimedes' Principle of Buoyancy

Condition for Flotation. An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if [latex]text{F}_text{B} = text{mg}[/latex]. But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is ...

Sep 28, 2018· Buoyancy is the force that enables boats and beach balls to float on water. The term buoyant force refers to the upward-directed force that a fluid (either a liquid or a gas) exerts on an object that is partially or completely immersed in the fluid. Buoyant force also explains why we can lift objects underwater more easily than on land.

Froth Flotation Process

process consists of several flotation cells together with cyclones, mills, and mixing tanks. For poly-metallic ore different flotation circuits and a grinding circuit can be combined in order to form a concentrator used for extracting several mineral types from the same ore. This is the case for the Garpenberg concentrator,
