Regime Design for Gold Ore Flotation by Air and Steam
2021-8-11 Abstract The flowchart is developed for gold ore flotation at the reduced impurity of the rougher flotation product with difficult middlings. The rougher flotation concentrate is subjected to scavenging by aerated air and hot steam mixture. In cold pulp slurry, the steam condensation heat is removed from bubbles to wetting films. With increasing temperature, the hydrophilic
