Kaiyang county, Guiyang, capital of Southwest China's Guizhou province, is a core area for high-quality phosphate deposits in China. To date, Kaiyang has verified 1.9 billion metric tons of phosphate reserves, with prospective reserves reaching three billion tons. It has established a stable production capacity of 10.9 million tons of phosphate ore annually, ensuring ample raw material supply for the phosphate chemical industry chain.

Kaiyang's high-grade phosphate ore exceeds 32 percent, accounting for over 80 percent of the nation's reserves. It features high phosphorus pentoxide content, low impurities, and valuable associated resources such as fluorine and iodine, with an average fluorine content exceeding 3.05 percent. This high-grade ore can be directly utilized without complex beneficiation, significantly reducing production costs. It serves as a premium raw material for producing high-end phosphate chemical products and new energy battery materials.

As the leading project in Kaiyang's new energy battery materials industry chain, Guizhou Anda Energy Technology Co has established an annual production capacity of 150,000 tons of iron phosphate and 150,000 tons of lithium iron phosphate. It ranks among the top tier in the domestic industry, with products directly supplied to leading power battery companies like BYD. In 2025, Kaiyang achieved a total industrial output value of 37.4 billion yuan ($5.5 billion), a year-on-year increase of 25.1 percent, steadily advancing towards its goal of developing a hundred billion-yuan-level phosphate and fluorine chemical industry cluster.
