How Does Float Machine Work?

A float machine separates minerals based on their surface properties. The working principle of flotation machine involves these steps:

  • Preparation: The ore is ground into fine particles and mixed with water to form a slurry in a flotation cell.
  • Reagent Addition: Chemicals (froth flotation reagents) are added to the slurry to make the desired minerals hydrophobic (water-repelling).
  • Aeration: Air is pumped into the slurry, creating bubbles. The hydrophobic mineral particles attach to the air bubbles.
  • Froth Formation: The mineral-laden bubbles rise to the surface, forming a froth layer.
  • Collection: The froth, containing the valuable minerals, is skimmed off, while the unwanted materials (gangue) remain in the slurry in flotation cells.

In the flotation machine, after adding the pharmaceutical treatment of the slurry, through the agitation of the inflatable, so that some of the mineral particles selectively fixed on top of the air bubbles; floated to the surface of the slurry is scraped to form a foam product, and the rest of the slurry is retained in the slurry, in order to achieve the purpose of separating the minerals. There are many structural forms of flotation machine, the more commonly used is the mechanical agitation flotation machine.

What is Work Process of Using Flotation Machine Float Mining?

The work process when using a flotation machine in float mining includes:

  • Crushing and Grinding: The ore is crushed and ground into a fine powder to liberate the minerals.
  • Mixing and Conditioning: The ground ore is mixed with water and froth flotation reagents in a conditioning tank to prepare the mineral surfaces for separation.
  • Flotation: The conditioned slurry is fed into the flotation cell, where air is introduced to create bubbles and the desired minerals attach to the bubbles.
  • Concentrate Collection: The froth containing the valuable minerals is collected as concentrate.
  • Tailings Disposal: The remaining slurry, containing the unwanted materials, is sent to tailings ponds for disposal.

Flotation Process

Flotation process refers to the method used in the flotation process of a mineral. Flotation is the same as other mineral processing methods, to do a good job of material preparation before selection, that is, the ore should be milled and graded to achieve the concentration of fineness suitable for flotation. In addition, flotation has the following basic operations: slurry adjustment and add flotation chemicals, change the mineral wettability so that mineral particles attached to the bubble. Mineralization of bubbles. Selective attachment of mineral particles to air bubbles is the basic behavior of the flotation process. Flotation is a beneficiation method based on the different wettability of minerals by water. Generally, the nature of minerals easy to float and difficult to float is called the floatability of minerals. Flotation is the use of the difference in the floatability of minerals to separate minerals.

What Industries Use Floating Machine?

Floating machine technology is used across multiple industries:

  • Mining: For concentrating valuable minerals from ores.
  • Wastewater Treatment: For removing suspended solids, oils, and other contaminants.
