In the electrolysis process of antimony ore slurry, circulation and filtration equipment plays a vital role. The following is a detailed introduction to these equipment:

1. Circulation equipment

Circulation pump

Function: The circulation pump is mainly used to circulate the slurry in the electrolytic cell. Through the circulation flow, the concentration polarization can be eliminated, the electrolysis efficiency can be improved, and the valuable metals in the slurry can fully participate in the electrolysis reaction.

Features: The circulation pump usually has high corrosion resistance and wear resistance to adapt to the complex composition of the slurry and the chemical changes during the electrolysis process. At the same time, the design of the circulation pump also needs to consider its flow rate, head and other parameters to meet the circulation needs of the electrolytic cell.

2. Filtration equipment

Filtration device

Function: The filtration device is mainly used to filter the slurry or electrolyte to remove impurities or solid particles. This helps to keep the electrolytic cell clean and improve the electrolysis efficiency. It also helps to protect the subsequent processing equipment from damage by solid particles.

Type:

Plate and frame filter press: The plate and frame filter press is a common filtration equipment that uses a filter chamber formed by alternating filter plates and filter frames to filter the slurry. In the filtration process, the filter cloth plays a key role. It can intercept the solid particles in the slurry, while the filtrate flows out through the filter cloth. The plate and frame filter press has the advantages of simple structure, easy operation and good filtration effect.

Vacuum filter: Vacuum filter is another common filtration equipment. It uses the negative pressure generated by the vacuum pump to attract the filtrate in the slurry and intercept solid particles at the same time. The vacuum filter has the advantages of fast filtration speed and large processing capacity, and is suitable for occasions where a large amount of slurry is processed.

3. Equipment selection and configuration

When selecting and configuring circulation and filtration equipment, the following factors need to be considered:

Slurry characteristics: including parameters such as slurry particle size, density, viscosity, etc., which will affect the selection of circulation pumps and filtration effects.

Electrolytic cell requirements: The size, shape and capacity of the electrolytic cell will affect the flow and head requirements of the circulation pump, and will also affect the size and filtration capacity of the filtration device.

Process requirements: Different antimony slurry electrolysis processes may have different requirements for circulation and filtration, and it is necessary to select appropriate equipment according to specific process requirements.

In summary, circulation and filtration equipment plays a vital role in the antimony ore slurry electrolysis process. By rationally selecting and configuring these equipment, electrolysis efficiency can be improved, production costs can be reduced, and it also helps protect the environment.
