FRASER'S AIR-SAND PROCESS

Specialty Definition: FRASER'S AIR-SAND PROCESS

DomainDefinition

Mining

A dense-media process in which a dry, specific-gravity separation of coal from refuse is achieved by utilizing a flowing dense medium intermediate in density between coal and refuse. The dense medium is formed by bubbling air through a mass of dry sand, 30 to 80 mesh in size. The air dilates and fluidizes the sand mass, causing it to behave somewhat as a heavy liquid. The coal floats on the aerated sand mass and the refuse sinks.Syn:air-sand process. (references)
