Solid concentration for froth concentrate pumping (4 replies)

3 weeks ago

Dear All 

I need to transfer some phosphate froth concentrate (coming from flotation cells) and feed a dewatering hydrocyclone. What should be my average solid concentration for a correct pumping ? I consider 21% solid (weight basis). Do I need to dilute any more? Is a froth pump well suited to feed my hydrocyclone ?

Kind regards

Hi Romain,

this will pump fine. No need to dilute further. Be sure to have a good head over your pump intake for steady feed pressure. I see no issues.

Dear sir,

20-25 %solids by weight fine. To avoid  froth pump u can use dewatering screw instead of dewatering cyclone.

Thank you for your answers. 

I am in contact with a pump manufacturer and he advise a slurry pump instead of a froth pump, because I want to feed a Hydrocyclone. Does it seem a good application for a slurry pump ? Have you ever met this configuration ?

A slurry pump is best. Froth (air) does not pump.
