Froth Floatation Process which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth The gangue particles being heavier remain behind at the bottom of water tank The froth is separated and concentrated sulphide ore is obtained from it Desulfurization and demineralization of asphaltite using combination of froth flotation and aqueous caustic leaching Article in Energy Exploration Exploitation 26(2) 133-142 April 2008 with
The mechanism of the carrier flotation process is ascribed to the electrostatic forces between the slightly negatively charged carrier particles and relatively highly negative particles (-40 mV) of fine 1 2 Carrier flotation for desulfurization and deashing of difficult-to-float coals 669 lignitic coal The linear regression method shows that the relationships between flotation parameters and the recovery and collision probability of flotation can achieve correlation coefficients (R 2) of 0 54 and 0 87 respectively A feed-forward artificial neural network with 3-3-3-2 arrangement is able to simultaneously estimate the recovery and collision
