The feed edge of the table has a water spray bar. This water is adjusted to provide a gentle wash across the table. The action of the table creates inverse classification and stratification, i.e. each mineral of a certain specific gravity is arranged according to size. Due to the motion the bed moves to the concentrate end. As the height of the ...
