Where is the location of the flotation reagent dosing? What is the dosing order?

The media conditioning agent is typically added to the ball mill to eliminate the deleterious effects of ionization on flotation that is activated or inhibited.

The inhibitor should be added before the collector and usually also added to the mill.

Activators are often added to blending tanks or flotation machines.

Collector of insoluble (e.g. baiyao, coal oil), to promote dispersion and dissolution time, growth and minerals, but also often added in the mill. The yellow medicine is generally added to the overflow of the classifier, and is also added to the adjustment tank or the flotation machine.

The foaming agent is added to the adjustment tank or flotation machine.

The usual dosing order is:

1) When flotation of raw ore, first add regulator → inhibitor → collector → foaming agent.

2) Add activator→collector→foaming agent first when flotation is inhibited.

In order to improve the efficiency of the action of the agent, it is usually necessary to stir the agent with the slurry for a certain period of time before the flotation, and the length of the stirring is mainly related to the solubility of the agent. Usually 5-20 minutes, short 1-5 minutes. In addition, the choice of dosing location should also consider the nature of the ore. For example, some copper sulfide - iron ore flotation plant xanthate was added to the mill, resulting in improved sorting index.
