For the flotation process, whether a mineral processing obtains the satisfactory mineral processing indexes depends largely on the flotation reagent system, including the type of flotation reagent, the amount of flotation reagent, the method and location of flotation reagent added. In general, Xinhai helps customers to determine the scientific and reasonable flotation reagents system according to the results of mineral processing test, and continuously adjusts the flotation reagents system in the production, so as to obtain the ideal technical and economic indicators.

Flotation Reagent selection

How to confirm the dosage of flotation reagent?

In the flotation process, Xinhai mine research institute suggests that the appropriate dosage of flotation reagents should be selected according to the results of mineral processing tests. In the actual production, Xinhai mine research institute will adjust the dosage of flotation reagents according to the specific situation if the material composition changes, otherwise the dosage of flotation reagents cannot be changed arbitrarily.

Flotation is a method commonly used in the industry to separate gold ore, and is suitable for processing fine-grained, infiltrated and complex ore. In the flotation process, the hydrophobicity of the mineral surface is changed by selective adsorption between the flotation agent and the target mineral, and finally the mineral particles with strong hydrophobicity are adsorbed on the bubbles and float. Flotation reagents are divided into three categories according to their functions: collectors, foaming agents and regulators, just like conventional flotation reagents.

Collector: Add it to the agitation tank or flotation cell with the foaming agent, while the insoluble collector (such as cresol aerofloat, white catching agent, kerosene) is often added to the grinding mill to promote its dispersion and increase the action time with minerals.

Regulator: Add regulator to the grinding mill firstly, which not only make the inhibitor and collector play the role in the appropriate pulp, but also eliminate some unavoidable ions that are harmful to the flotation effect.

Inhibitor: Inhibitor: Add it to the grinding mill before the collector,which can promote the interaction between the inhibitor and the inhibited minerals early.

Activator: Add it to the agitation tank for mixing with the slurry, which can promote the action between activator and activable minerals.
