With the rapid development of the new energy vehicle industry, the demand for high-performance green batteries is growing. As the core component of new energy vehicle batteries, the quality and output of lithium battery materials directly affect the development of the entire industry chain. As one of the important raw materials for the precursor of lithium battery ternary positive electrode materials, cobalt sulfate has huge market demand potential. In the production process of cobalt sulfate, extraction operation is a key technology.
The production of cobalt sulfate usually includes the following steps: roasting, acid leaching, filter pressing, washing, copper extraction, electrolytic deposition of copper-cobalt ore, etc., and finally obtaining the product of electrolytic copper. Among them, most of the copper raffinate (containing cobalt raffinate) returns to the acid leaching stage, while a part enters the subsequent steps of neutralization and iron removal, extraction and impurity removal, concentration and crystallization, drying and packaging, and finally produces cobalt sulfate products.
Unique Cobalt Sulfate Extraction Process
Extraction is a technology that uses the difference in solubility of substances in different solvents to achieve separation. In the production process of cobalt sulfate, the required cobalt components can be effectively separated by selecting a suitable solvent to add to the mixture. The characteristics of the Extraction Equipment centrifugal extractor include fast mass transfer, short production cycle, easy continuous operation and automatic control, high separation efficiency, large production capacity, low energy consumption, and low equipment investment cost.
Three Steps of Cobalt Sulfate Extraction Operation
1.Mixing: the feed liquid and the extractant are fully mixed.
2.Separation: the mixed feed liquid is separated into the extraction phase and the raffinate phase.
3.Solvent recovery: the extractant is recovered for reuse.
The mixing and separation operations can be completed in one equipment at the same time. Centrifugal extractors or mixer settlers are generally used in industry.
Comparison Between Centrifugal Extractors and Mixer Settlers
Traditional mixer settlers have problems such as large liquid inventory, large floor space, low separation efficiency, and easy emulsification. In response to these problems, Zhengzhou Tiei Extraction Company have launched the CWL-M series centrifugal extractor, which is a new type of efficient extraction equipment, especially suitable for the extraction process of cobalt sulfate. Compared with traditional mixer settlers, the CWL-M series centrifugal extractor has the following significant advantages:
1.Reduce the liquid inventory in the equipment: Reducing the liquid inventory helps to improve the extraction efficiency and reduce energy consumption.
2.Improve separation efficiency: The CWL-M series centrifugal extractor uses the centrifugal force generated by high-speed rotation to quickly separate the liquid and achieve better separation effect.
3.Avoid emulsification: Due to the reasonable internal structure design of the centrifugal extractor, the occurrence of emulsification can be effectively avoided.
4.Reduce energy consumption: Due to the high mixing intensity, the material can reach a balanced state in a very short time, and the energy consumption is significantly reduced.
5.Increased processing capacity: The CWL-M series centrifugal extractor has a stronger processing capacity and can meet the needs of large-scale production.
6.Easy to automate and control: The centrifugal extractor supports online monitoring, which enables automated control and simplifies the operation process.
