How to master the dosage of beneficiation reagent


Theoretical research and concentrator experience show that the dosage of various beneficiation reagents is the key to obtain good flotation and beneficiation technical indexes. Mineral processing reagents mainly refer to collectors, foaming agents, activators and inhibitors. Nowadays, the application of mineral processing reagents is more and more widely used. However, many people have doubts about the dosage of mineral processing reagents. What will happen if the dosage of dressing reagents is too much or too little?


When the dosage of reagent is not enough, the hydrophobicity of the mineral surface to float is not enough, which will reduce the recovery rate. In preferential flotation of polymetallic ores, too much collector will cause the inhibited minerals to float. In this way, not only the quality of concentrate is reduced, but also the competitive adhesion of restrained minerals on the surface of bubbles will reduce the floating opportunity of target minerals and reduce the recovery rate. It is also often found that when the collector is excessive, the foam is over mineralized, the foam layer is sinking, and the foam is difficult to discharge. The amount of collector is insufficient, the mineral is not enough hydrophobic, the recovery rate is reduced, the dosage is too high, the quality of concentrate decreases, and the separation flotation is not easy. The amount of foaming agent is insufficient, the foam stability is bad, the dosage is too high, the "running trough" phenomenon occurs, the dosage of activator is too small, and the activity is not good, the dosage is too high, which will destroy the selectivity of flotation process, and the dosage of inhibitor is not enough. If the ore grade is low and the reagent is excessive, the minerals that should float out will be restrained and the recovery rate will be reduced.


From the above content, we can draw that the dosage of mineral processing agent is required, and it must be appropriate. Too much or too little will affect the mineral processing index. Therefore, attention must be paid to the dosage problem when using mineral processing reagent.
