Do You Use Flotation Reagent Right in the Flotation Process?

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.

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.

How to confirm the dosage of flotation reagent

01

Due to the different ore properties, the dosage range of flotation reagent is also different. Even for the same type of ore, there are also some differences in the formation of ore deposit, so the content of useful minerals and gangue vary, and the dosage of flotation reagent required in the flotation process are also different.

Each flotation reagents usually do not interact with minerals alone, so it cannot be viewed in isolation. For example, the collector and inhibitor often interact in the same system, the activator and inhibitor also interact in the same system.

How to select the appropriate place, order and way of flotation reagent added?

01Dosing location

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.

02Dosing order

Usually, Xinhai mine research institute will determine the dosing order according to the situation:

Raw ore: PH regulator - collector - foaming agent.

Inhibited ore: Activator - collector - foaming agent

Dosing order

03Dosing method

One-time dosing: Add all the flotation agents in one time before the roughing operation.

Application: Generally, one-time dosing method is suitable for those reagents that are soluble in water, cannot be taken away by the froth and is not easy to react in the pulp, such as lime, soda.

Advantage: high reagent concentration, easy to add.

Several-time dosing: Add the flotation reagents in several times along roughing, concentrating and scavenging. Generally, add 60%~70% of the total amount before the flotation stage, and the rest of reagents is added to the appropriate locations in batches.

Application: Oxidizing, labile and reactive reagents, such as xanthate, sulfur dioxide gas; Reagents that are insoluble in water and can be taken away by the froth, such as oleic acid, aliphatic amine; Reagents required a strict dosage, such as sodium sulfide.
