In the era of new energy, the importance of lithium as a key element is self-evident. With the rapid development of electric vehicles and energy storage systems, the demand for high-purity lithium is increasing. How to extract lithium from spodumene efficiently and environmentally friendly has become the focus of industry attention. Today, we discuss an advanced processing technology - acid roasting of spodumene using a rotary kiln, which is leading lithium resource development into a new era.


[Overview of rotary kiln acidification roasting process]

The rotary kiln is an industrial equipment widely used in the field of mineral processing, known for its continuous operation, uniform heating and good gas-solid contact characteristics. For spodumene, acid roasting in a rotary kiln can achieve a more efficient lithium extraction process. The process usually includes the following steps:

(1) Pretreatment: Mix spodumene with an appropriate amount of acidic substance (such as sulfuric acid) to form a slurry.

(2) Feeding: Feed the prepared slurry into the rotary kiln.

(3) Calcination: In a rotary kiln, by precisely controlling the temperature and atmosphere conditions, the lithium in spodumene reacts with the acid to generate soluble lithium salts and promote the release of lithium.

(4) Cooling and collection: The material after high temperature treatment is cooled and then subjected to subsequent leaching process to extract lithium.


【Technological innovation, improving efficiency】

The advantage of using a rotary kiln for acid roasting is that it can provide a uniform heating environment, ensuring that spodumene is heated uniformly throughout the process, thereby improving the lithium conversion rate. In addition, the design of the rotary kiln allows for a larger processing volume, making it suitable for large-scale industrial production. At the same time, through fine control of roasting parameters, the generation of by-products can be effectively reduced, improving the economy and environmental protection of the overall process.


【Green manufacturing, sharing a better future】

In the face of global climate change challenges, the use of rotary kiln acidification roasting of spodumene not only helps to improve the utilization rate of lithium resources, but also reflects the sense of responsibility for environmental protection. Compared with traditional methods, this process reduces harmful gas emissions, lowers energy consumption, and achieves a cleaner production method. This is not only an effective protection of natural resources, but also a concrete practice of leaving behind the beautiful vision of blue skies and green land for future generations.


【Conclusion: Work together to promote the new energy revolution】

Looking ahead, we will continue to optimize and improve the technical solution for rotary kiln acidification roasting of spodumene, and strive to create a more efficient and environmentally friendly lithium extraction production line. We hope that through our efforts, we can contribute to the development of the global new energy industry and jointly embrace a low-carbon, sustainable future. Let us join hands and use the power of technology to light up a green tomorrow!
