Matters needing attention in the flotation method of flotation machine

1. Mineralization of bubbles. The selective attachment of mineral particles to bubbles is the basic behavior in the flotation process. Generally, the floatability of minerals is called the floatability of minerals. Flotation is the use of the difference in the floatability of minerals to sort minerals. After the flotation agent is processed, the floatability of the mineral can be changed, so that the mineral to be floated can be selectively attached to the bubbles, thereby achieving the purpose of beneficiation.

2. The adjustment of pulp and the addition of flotation reagent. The purpose is to cause the difference in mineral surface properties, that is, to change the wettability of the mineral surface, adjust the selectivity of the mineral surface, so that some mineral particles can be attached to the gas, while others cannot be attached to the bubbles.　　

3. Stir and cause a lot of bubbles. With the aid of the aeration and stirring effect of the flotation machine, the air in the slurry is dispersed to form a large number of bubbles, or the air dissolved in the slurry is caused to form a micro-saturation.　　

Flotation is the same as other beneficiation methods. It is necessary to do a good job of material preparation before separation to achieve the concentration fineness suitable for flotation. In the flotation process, the ups and downs of minerals are almost independent of mineral density. For example, chalcopyrite and quartz, the former has a density of 4.2 and the latter has a density of 2.68, but the heavy mineral chalcopyrite is easy to float up, and quartz sinks at the bottom instead.

Research has found that the floatability of minerals is related to their affinity for water multi-slot flotation machines. Minerals that have a high affinity for water and are easily wetted by water are difficult to adhere to bubbles and are difficult to float. However, minerals that have a low affinity for water and are not easily wetted by water tend to float.
