flowing-film concentration

flowing-film concentration

[¦flō·iŋ ¦film käns·ən′trā·shən]

(mining engineering)

A concentration based on the fact that liquid films in laminar flow possess a velocity which is not the same in all depths of the film; by this principle lighter particles of ore may be washed off while the heavier particles accumulate and are intermittently removed.
