As of early September, seven privately-owned iron ore mining companies and a building materials firm have established operations near Yihua Chuxing Chemical Company. These companies are interested in the company’s phosphate slag and pyrite residue, which they use as raw materials to produce items such as iron concentrate powder, gypsum boards, and gypsum blocks. At one point, what was once Baozhe’s chemical waste became a "hot topic."
Yihua Chuxing Chemical Company is a key production base for phosphate compound fertilizers and fine chemicals in Hubei Province. This year, the company invested 750 million yuan to build a new facility capable of producing 1 million tons of high-concentration compound fertilizer, 30,000 tons of salt chemicals, and 50,000 tons of methyl chloride annually. As the scale of its chemical operations continues to expand, it also generates over one million tons of pyrite slag and phosphate slag each year, posing environmental challenges.
To address this issue, the plant has shifted its approach, viewing chemical waste not as a burden but as a "misplaced resource." By doing so, it has attracted external investment and introduced recycling-based processing projects. For example, the seven private iron ore mining companies that import raw ore use advanced techniques like water separation and magnetic separation to produce iron ore fines, which are then sold to domestic steel manufacturers. The small amount of residual material left after iron extraction is further processed and used as an additive in cement plants.
The arrival of these iron ore processing enterprises has transformed Chuxing’s waste slag into a valuable asset, creating a circular economy that benefits both the environment and resource efficiency. This innovative model not only reduces pollution but also promotes sustainable development in the region.
