The induced air flotation machine was invented by William Fagergren in the 1930's in the Salt Lake Valley of Utah. Induced air means that the rotor for the froth flotation machine draws in atmospheric air, rather than having an air compressor or blower providing "forced air".

How much flotation foam do I need for my boat?

To determine how much flotation foam you need for your boat, you should calculate the volume of the boat's hull and then consult the U.S. Coast Guard regulations for the required amount of flotation foam based on the boat's size and weight. It is important to ensure that your boat meets the necessary flotation requirements for safety on the water.


How are buoyancy and flotation linked?

Buoyancy is the force that allows an object to float or be supported when submerged in a fluid. Flotation is the process by which an object rises to the surface of a fluid due to the buoyant force acting upon it. In simplest terms, buoyancy causes flotation.


What physical property does flotation rely on on an ore?

Flotation relies on the physical property of hydrophobicity, which refers to the tendency of certain minerals to repel water and cling to air bubbles. In an ore flotation process, the hydrophobic minerals attach to air bubbles and float to the surface, separating them from hydrophilic minerals that remain in the water.


What is the upward force of displaced fluid causing flotation?

The upward force of displaced fluid that causes flotation is called buoyant force. This force is equal to the weight of the fluid that is displaced by the object placed in the fluid. When this buoyant force is greater than the weight of the object, the object will float.


Who discovered the law of flotation?

The law of flotation was discovered by Archimedes, a Greek mathematician and scientist, in the 3rd century BC. He determined that an object will float in a fluid if the weight of the fluid displaced by the object is equal to the weight of the object itself.
