The concentrator is one of the most important equipments in the current mineral processing equipment. The working quality of the equipment directly affects the concentration of the slurry. At present, we usually use the method of sedimentation and concentration.

Precipitation concentration is the dehydration process in which the ore particles are deposited from the slurry by their own gravity. During the precipitation process, the ore particles settle according to the law of the movement of solids in the medium. In a very short period of time after the sedimentation begins, the ore particles settle down with acceleration, and then gradually balance with the gravity of the ore particles due to the resistance of the medium. The ore particles gradually move at a constant speed, and the speed is called the final velocity of sedimentation. In the pulp, the size of the ore group is not uniform, and the purpose of sedimentation is to hope that all the ore particles are settled to obtain a clear liquid, so the sedimentation velocity of the ore particles must be calculated according to the final velocity of the minimum particles. The speed is called the final velocity of the settling. In the pulp, the size of the ore group is not consistent. It can be seen from the above formula that the particle size of the ore has the greatest influence on the sedimentation velocity, because the square of the particle size is proportional, so the finer the ore, the slower the sedimentation rate. Therefore, in the sedimentation process, the most difficult to settle is the fine slime. The more mud in the pulp, the more difficult it is to clarify, and it is often suspended in the slurry. The main reason is that there is an electric double layer on the surface of the fine mud. With the same-sex charge, mutual exclusion. Due to the Brownian motion, the fine mineral slurry tends to be balanced. In the production practice, in order to accelerate the sedimentation of the fine ore particles, a certain agglomerate may be added to the slurry to improve the precipitation concentration effect of the proud ore particles.
The viscosity of the slurry also significantly affects the sedimentation rate of the particles. It can be seen from the above that it is inversely related to Lu Cheng. The viscosity of the pulp decreases with increasing temperature. Therefore, the slurry is heated to accelerate the sedimentation of the fine particles. However, heating the slurry requires energy, and it is necessary to consider the economic effect when it is applied.
In addition, the lower the concentration of the slurry, the smaller the density of the medium, and the mutual interference of the ore particles is also small, so it is advantageous for the sedimentation of the particles. It can be seen that the lower the concentration of the slurry, the better the sedimentation.
