Antimony is an important chemical raw material, widely used in alloys and flame retardant materials. However, antimony wastewater discharge can cause pollution to the environment. Therefore, the development of efficient antimony removal technology is particularly important. The combined extraction centrifugal extractor provides an effective technical means for the extraction of antimony.

Environmental properties of antimony

Antimony is usually present in water in the form of antimony ions (Sb³ + or Sb V +). The excessive presence of antimony can cause damage to the growth of aquatic organisms and pose risks to human health. Therefore, the removal of antimony from wastewater is an important task of water pollution control.

Separation mechanism of combined extraction centrifugal extractor

The combined extraction centrifugal extractor realizes the efficient separation of antimony ions in wastewater through the centrifugal force generated by high-speed rotation. The specific steps include:

1. Feed operation: the antimony containing wastewater is injected into the equipment.

2. Centrifugal treatment: In the process of high-speed rotation, antimony ions will settle due to their density.

3. Precipitation collection: The settled antimony is collected through the discharge system, which is convenient for subsequent treatment.

Optimized extraction conditions

The key conditions for improving the extraction efficiency of antimony include:

1. Centrifugal speed: appropriately increase the speed can accelerate the settlement of antimony, the recommended range is 4000-8000 rpm.

2. Treatment time: Extending the treatment time can generally improve the extraction rate of antimony, usually 20-30 minutes.

3. PH adjustment: The separation effect of antimony is better under neutral to slightly acidic conditions.

Follow-up treatment and resource recovery of antimony

The extracted antimony precipitates can be recovered by roasting, chemical treatment and other methods. The reuse of antimony can not only reduce environmental pollution, but also provide raw materials for related industries.

The research on the extraction of antimony from industrial wastewater by combined extraction centrifugal extractor provides important technical support for water pollution control. With the continuous progress of technology, its application prospect will be broader.
