In the elutriation leg of a commercial crystallizer containing a mixture of coarse and very fine crystals of the same material, a liquid is pumped vertically upward. The liquid velocity is adjusted such that it is slightly lower than the terminal velocity of the coarse crystals only. Hence
- the very fine and coarse crystals will both be carried upward by the liquid
- the very fine and coarse crystals will both settle at the bottom of the tube
- the very fine crystals will be carried upward and the crystals will settle
- the coarse crystals will be carried upward and the very fine crystals will settle
