SF Flotation Cell
SF Flotation Cell/Machine Working Principle When the rotor is rotating, an internal vacuum is created both in the upper and lower blade zone. Ambient air is drawn through an air intake pipe and standpipe by the action of the upper blade, the bubbles are then micronized and make the minerals easier to stick on the bubbles.
Technological assessments on recent developments in fine …
Froth flotation was undoubtedly the most innovative and groundbreaking discovery for mining in the 19th century (Wills and Finch, 2015).Nevertheless, it did not last long that scientists recognized its limitations for extremely fine and coarse particles, which has remained a long-standing unsolved issue in the mineral processing field (Gaudin et al., 1931).
Froth flotation process and its application
Froth flotation is one of the steps which is generally performed before roasting and it deals with the surface chemistry of liquids and of the minerals to be separated.

Depressants and activators When more than one sulfide ores are present in the cell, depressants are used to depress certain minerals and promote the selective flotation of desired minerals. During such selective flotation processes
SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
