Flotation Process: Extracting Minerals from Ores
The flotation process is a widely used method for separating minerals from their ores. It relies on the differences in surface properties of the minerals to be separated. Here are the steps involved in the flotation process: Grinding: The ore is first crushed into a fine powder through the process of grinding.

Full-Scale trial of the REFLUX™ flotation cell
Abstract. A 2 m diameter REFLUX™ Flotation Cell was fed at roughly 210 m 3 /h, equivalent to a flux of 1.9 cm/s, about twice the maximum rate used in conventional flotation cells. The coal feed slurry had 59–64 wt% head ash and nominal size range −0.100 mm (Sauter mean size 0.004 mm). The air, wash water and underflow rates were …

A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …
