Description

TECHNICAL FIELD

[0002] The flotation machine is one of the most important separation devices in the field of mineral processing, and is widely used in various metal and non-metal mines. In the prior art, air is introduced into the ore pulp through a hollow shaft pipe, and the ore pulp is stirred by rotating the stirring blades at the end of the shaft pipe, so that the air is dispersed into the ore pulp to form bubbles. The bubbles will capture mineral particles and rise to the upper part of the ore pulp tank, and overflow to the mineral recovery tank outside the ore pulp tank. When the size of the ore pulp tank increases, the distance between the foam and the edge of the ore pulp tank will increase, which means that the foam containing minerals cannot leave the ore pulp tank faster. The longer the foam stays in the ore pulp tank, the greater the probability of foam aggregation, which will cause the selected minerals to fall back to the ore pulp tank, reducing the separation effect.
