Nonferrous Smelting covers a wide range. Our company is mainly engaged in the treatment of nitrogen oxide waste gas and other acid waste gas in the process of gold smelting. In the non-ferrous smelting process with the nature of hazardous waste, the flue gas produced by pyrometallurgical smelting is desulfurized and sold out. Treatment of acid waste gas generated in the electrolysis process. In the production of manganese, molybdenum, copper, nickel, zinc and aluminum, the waste gas generated in various process sections shall be treated. The main treatment process needs more specific technical parameters such as flue gas temperature, flue gas composition and flue gas concentration to determine the treatment process.
