"Steady-state rejection of impurities has been established at 99.9%. Notably, sodium concentration
has been reduced from 95,460 mg/L to 61 mg/L in the concentrate."

These results indicate a very impressive performance in terms of impurity rejection and sodium removal during the lithium extraction process. Here's a breakdown of the key points:

Impurity Rejection:

• Steady-state rejection of impurities has reached 99.9%. This is an exceptionally high level of purity, meaning that only 0.1% of the original impurities remain in the final product.
• This level of impurity rejection is crucial for various applications of lithium, particularly in battery production, where even small amounts of impurities can significantly affect performance and lifespan.

Sodium Removal:

• The initial sodium concentration in the feed was 95,460 mg/L, which is quite high.
• The process successfully reduced the sodium concentration to 61 mg/L in the concentrate. This represents a removal efficiency of 99.94%.
• Controlling sodium concentration is important for several reasons:
  • High levels of sodium can impact the efficiency and stability of lithium batteries.
  • Reducing sodium concentration facilitates further purification steps in the lithium extraction process.

Overall:

• The combined data on both impurity rejection and sodium removal demonstrates a highly effective and selective process for extracting lithium.
• This level of performance is essential for meeting the stringent purity requirements for lithium applications in various high-tech industries, especially in the context of clean energy technologies.
