The production of barium sulfate involves several stages, including mining, beneficiation, and processing. The first step is to extract barium sulfate from the earth, which is typically done through underground or open-pit mining methods. Once the ore is extracted, it undergoes beneficiation to separate the barium sulfate from other impurities. This process may include washing, grinding, and flotation techniques.

The country's rich titanium resources have been a cornerstone for the development of this sector. With approximately 6618 million metric tons of titanium ore reserves, China has been able to establish a robust titanium dioxide production infrastructure. These reserves are primarily located in regions such as Sichuan, Yunnan, Guangdong, and Hainan, which have become major hubs for titanium dioxide production.
