froth floatation for fly ash beneficiation

Title: Separation of High LOI Fly Ash Authors - International Cement Review

Wet Separation of Fly Ash Several potential wet processes that can recover unburned carbon from fly ash include: (1) heavy medi a cyclone; (2) froth flotation; (3) selective flocculation; and (4) oil agglomeration. Of these four processes, froth flotation is the most commonly applied. Use of heavy media cyclones is economically not attractive
