Background

In the process of mining operation, some metallurgical enterprises are influenced by the nature of ore sources and the process flow of the selected factory, the concentration of tailings of the selected factory is 18.1-28.7%, the granularity is fine, and the settling speed is slow, so that a proper amount of flocculating agent needs to be added into the tailings concentration to accelerate the settling speed, the settling concentration time is shortened, the concentration of the tailings is increased to 64%, and return water is clear and returns to the selected factory for production and use. Because the flocculating agent can not be completely adsorbed by the tailings, the residual amount enters the separation process flow of the separation plant along with the backwater of the filling station, and is agglomerated and wrapped with fine mineral particles, so that part of target minerals can not be separated and recovered timely and effectively, the recovery rate of the target mineral copper metal of the separation plant is reduced from 84.57% to 82.54%, and certain metal loss is caused. In order to reduce the metal loss and the influence of the residual flocculant in the backwater on the flotation index, the consumption of the flocculant needs to be reduced on the premise of meeting the production requirement, so that the residual quantity of the flocculant in the backwater is reduced.

The existing method for adding the flocculating agent is to flow ore pulp through a stirring tank, add the flocculating agent into the stirring tank and mix the flocculating agent and the ore pulp through stirring.
