Will flotation column reduce production recovery?

At present, the flotation columns on the market are mainly divided into two categories: inflatable flotation column and jet flotation column (swirl), which have their own advantages. In the past ten years, the air flotation column is mainly used in nonferrous metal mines, and the jet flotation column is mainly used in coal preparation. The following is mainly about the influence of the inflatable flotation column on the recovery rate.

In the aspect of improving grade and saving energy, the advantages of the inflatable flotation column are very obvious. Because it can improve the grade very fast and the flotation precision is very high. It is suitable for minerals with high flotation speed, but not ideal for minerals with low flotation speed and long flowsheet.

The air flotation column has a good effect on the collection of mineral particles between 50um and 10um, which is his main advantage, but it has a poor effect on the collection of particles above 100 mesh, especially the intergrowth. At present, inflatable flotation column and traditional flotation machine need to be used together to form a "column machine combination" process. Such configuration can not only ensure the recovery rate, but also improve the concentrate grade.

To sum up: whether the flotation column will affect the recovery cannot be generalized. As a new type of mineral processing equipment, the flotation column has obvious advantages, but it also has its application scope. Before using the flotation column, it is necessary to analyze whether the mineral is suitable for using the flotation column, which kind of flotation column is suitable, and the type selection (size, height) of the flotation column is also very important. So, to make good use of flotation column, we need to understand it first.
