No. 30 "Sub-A" Flotation Machines are ideal for large tonnage operations, as each bank ...

Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, whereas hydrophilic …

Flotation machines constitute the basic equipment for useful minerals recovery from non-ferrous ores and other raw materials by flotation. They can operate also as individual flotation cells. Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to …
