## About

Based in Beijing, China and founded in 2023, Chuncui Separation initially focused on extractants for copper and battery metal recovery, later expanding into lithium extraction technologies. In July 2024, the company secured strategic investment from BAIC Capital, followed by a pre-series A round from Cowin Capital in July 2025 to support team expansion. The company develops and manufactures lithium extraction agents (Pextal-01, Pextal-02, and Pextal-03), copper extractants, flotation agents and acid mist inhibitors, serving industries involved in lithium processing, battery recycling and mineral separation. The company generates revenue through the sale of extraction agents and surfactant-based chemical products to industrial clients across lithium recovery, battery materials recycling and mineral processing sectors. The company aims to scale up its direct lithium extraction technologies, commercialize battery-grade lithium salt products and expand its R&D capabilities using proceeds from recent funding round.
