A fluidized powder heat treatment classification assembly includes a gas source. A fluidized bed is connected to the gas source via a metered connection. The fluidized bed includes a first output connected to a powder classifier via at least a first valve. The powder classifier includes a catch container operable to decelerate a gas flow from the output and operable to catch particles entrained in the gas flow.

A method of separating a mineral bearing particle from a fluid includes providing a housing along a surface of the fluid, moving the housing along the surface of the fluid with a driver, and applying a radio-frequency electromagnetic field to the fluid with a generator. Applying the radio-frequency electromagnetic field includes increasing a temperature of the mineral bearing particle contained within the fluid to a boiling point of the fluid whereby the mineral bearing particle transfers heat into the fluid.

A method for a reclamation of waste sand comprising bentonite binder, in which method it is subjected a thermal treatment to the waste sand for removing carbon and absorbed moisture from the bentonite binder in the waste sand, it is subjected a mechanical treatment to the thermally treated waste sand for mechanically separating the sand from the bentonite binder, and it is subjected a cooling effect to the sand separated from the bentonite binder. Additionally, it is introduced an apparatus for a reclamation of waste sand comprising bentonite binder, sand for a building industry product, a foundry sand, or a power plant boiler sand, and a use of reclaimed sand in a building industry product, in a foundry sand, or in a power plant boiler sand.
