Introduction
Sulfuric acid (H₂SO₄) is one of the most essential industrial chemicals used in the global manufacturing ecosystem. It is widely applied in fertilizer production, non-ferrous metal smelting, petroleum refining, chemical synthesis, wastewater treatment, and battery manufacturing. Due to its broad industrial use, sulfuric acid production capacity is often considered an important indicator of a country's chemical industry strength.
China has become the world's largest producer of sulfuric acid, supported by its massive fertilizer sector and integrated mining and metallurgical industries. A large portion of sulfuric acid is produced as a by-product during copper, zinc, and nickel smelting processes. For example, large copper producers such as Jiangxi Copper Company Limited generate significant amounts of sulfuric acid through their smelting operations, which are then supplied to chemical and fertilizer manufacturers.
In addition to large state-owned metallurgical enterprises, China also has numerous specialized sulfuric acid factories focused on industrial acid production and distribution. Among these companies, Lulong County Shuangyi Phosphorization Co., Ltd. has steadily expanded its industrial acid production capacity and developed stable supply relationships with domestic and overseas buyers.
