Inorganic chemical is called inorganic chemical industry for short. It uses natural resources and industrial by-products as raw materials to produce chemical products such as sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid and other inorganic acids, soda ash, caustic soda, synthetic ammonia, fertilizer and inorganic salts, including sulfuric acid industry, soda ash industry, chlor-alkali industry, synthetic ammonia industry, fertilizer industry and inorganic salt industry. In a broad sense，it also contains the inorganic non-metallic materials and fine inorganic chemicals production such as ceramics, inorganic pigments. The main raw materials of inorganic chemical products are minerals such as sulfur, sodium, phosphorus, potassium and calcium, as well as coal, oil, natural gas, air and water.
The main raw materials of inorganic chemical products are minerals such as sulfur, sodium, phosphorus, potassium and calcium (see inorganic salt industry), as well as coal, oil, natural gas, air and water. In addition, the byproducts in many industries and wastes are also raw materials for inorganic chemicals, such as coke oven gas in the coking production process in the steel industry. The ammonia contained in the steel industry can be recovered by sulfuric acid to make ammonium sulfate, chalcopyrite and galena. Sulfur dioxide in the smelting waste gas of mines and sphalerites can be used to produce sulfuric acid, etc.
