Titanium dioxide (TiO₂), renowned for its exceptional physical, chemical, optical, and pigment properties, serves as a critical raw material in consumer goods and chemical industries. Predominant production methods include the sulfate process and chloride process. The sulfate method, characterized by low feedstock requirements and mature technology, aligns with China’s industrial landscape, making it the dominant approach domestically.

Keysino pioneers eco-efficient TiO₂ recovery using patent-protected inorganic membrane technology. Tailored inorganic membranes selectively separate TiO₂ particles from pre-treated solutions, enabling high-purity recovery for reuse or resale. This method delivers superior efficiency, environmental compatibility, and process controllability, though it requires precise operational protocols and involves higher capital investment. Keysino’s innovation not only enhances resource utilization but also minimizes environmental footprint, setting new benchmarks for sustainable TiO₂ production.
