How to Operate a Flotation Circuit
Add as much air as your machine (froth) REQUIRES. A flotation machine needs deep froth in order to allow time for unwanted mineral to drain from the froth bubbles back into the pulp. Also, a high pulp level isn't so important in a cleaner cell, because recovery isn't what you're after so much as grade of concentrate.
