What is the flotation cell?

The flotation cell

Gold Flotation cells are used to separate non-ferrous metals such as copper, zinc, lead and gold, and non-metals like fluorite and talc. Flotation cells are widely used in mineral flotation like the pulp and paper flotation.

Flotation cell types and design

FTM flotation cell is mainly composed of a pulp tank, a stirring device, an aeration device, a foam device of discharging mineralization, an electric motor and so on. In actual production, the flotation cells are usually classified according to different methods of aeration and agitation. And they can be roughly divided into four basic types: mechanical-agitation flotation cell, gas-filled flotation cell, gas precipitation type (variable pressure type) flotation cell, inflatable mechanical flotation cell. FTM heavy machinery usually uses the mechanical-agitation flotation cell and gas-filled flotation cell for working.

What are the performance of the flotation cell?

• Effective volume: 0.37-8m³
• The flotation cell capacity: 0.2-8m³
• Reduce energy consumptiOn by 25-30%
• Better flotation efficiency
• Cover a small area and save construction costs
• High-output automation
• Environmental protection
• Convenient maintenance

The mechanical-agitation flotation cell has shallow foam and low foaming agent requirements, they are also used for producing foam. But due to incorrect discharging way, the foam is susceptible to contamination by undesired materials, which present in the bulk slurry.

How is flotation cell used to separate mixtures?

The operation of flotation cell

The structure diagram of flotation cell

Firstly, put the crushed ore into the agitation tank of FTM flotation, add water and chemicals into the tank during the grinding process, slowly adjust the slurry.

Then, continuously stir the tank, introduce air into the slurry, and make them form a large number of bubbles, some of which are not easily wet by water.

Mineral particles, generally appear to be hydrophobic, which can adhere to the bubbles and float to the surface of the slurry, together with the bubbles to form a layer of mineralized bubbles. Besides, other general mineral particles are not adhering to the slurry, so they are left in the slurry, finally, the mineralized bubbles containing specific minerals are discharged to achieve the purpose of mineral processing.

Popularization of knowledge
The foam of the flotation tank will certify the flotation effect, you can identify the flotation effect from the following aspects:

The virtual state of the foam, the size of the bubble, the color state of the pulp in the flotation cell, the change in foam gloss, the clarity of the foam profile, the brittleness of the foam, the thickness of the foam layer, and the sound of the foam.
