Flotation Plant Scale Up From A Pilot Plant - Froth Flotation ...

I do like the comment about flotation cell power intensity. As background, it is unusual to conduct a pilot plant for an established technology such as copper sulphide flotation, unless it is corporate policy (e.g. a major) or there is a need to produce samples for marketing. So there is rarely any need to understand this scale-up,...

Flotation Column Cell Carrying Capacity & Scale-Up - 911 Metallurgist

Mar 17, 2017 ... Flotation Column Cells can only 'carry' or recovery so much froth/concentrate for any given diameter. Unlike a mechanical cell on which you can just turn-on more air to recover more metal, column cells with not respond that way. A column cell can only carry so much froth to the concentrate launder.
