This is a flotation equipment in which high-speed ore slurry and air are mixed and mineralized in the spraying device, and the separation is realized in the cell. It can be divided into air suction type and compressed air type. (1) Typical air suction flotation cell is China FJC jet flotation cell series.

Introduction. Flotation is an important process in the minerals industry and most flotation is carried out using mechanically agitated cells ranging in volume up to 300 m 3.Separation of the particles of valuable minerals from the ore is achieved when particles of the valuable minerals preferentially attach to air bubbles and are floated to the surface …

The physical activities in a flotation cell involve the movement of solid particles driven by the flow of air and liquid. As illustrated in Fig. 1, Fig. 5, considering the different roles of pulp and froth in determining the cell dynamics, the flotation cell is divided into two sections: froth volume and pulp volume.The froth volume and pulp …
