FLOATATION REAGENTS. 1. Canoy, Claire E. 2B2- Chemical Engineering Technology Unit Operations Engr. Luna FLOATATION Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater ...
Abstract. Reactions in the process of flotation occur on the interface between minerals. Hence, the structure and properties of the solid–liquid interface play an important role in the flotation that determines the adsorption of flotation reagent on the mineral surface. The adsorption of water molecule on the MoS2 (001), Sb 2 S 3 (010), Cu 2 ...

It is known from soluble salt flotation practice that the K, Mg double salts of kainite (KClMgSO 4 3H 2 O), and carnallite (KClMgCl 2 6H 2 O) are difficult to float and must be converted to other salts such as ite (K 2 SO 4 MgSO 4 6H 2 O) and sylvite (KCl) in order to recover potash values. The flotation characteristics of these double salts have now been confirmed in some detail by ...

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air …
1 - Classification of Flotation Reagents. Modern classification of flotation reagents is based on the function of a particular reagent. On this basis, reagents are divided into collectors, frothers, regulators, and depressants. Collectors are a fairly large group of organic chemical compounds, which differ in chemical composition and function.
