Abstract:Current status and characteristics of China""s metal magnesium smelting industry were analyzed and environmental protection technologies were summarized. It pointed out some environment problems such as severe overcapacity, high pollution and energy consumption in production process, unreasonable emission standards and low environmental management standard. In order to promote green transformation and development of magnesium smelting industry in China, some suggestions were put forward, such as issuing industry environmental management guidance, conducting research on key environmental protection technologies for electrolytic magnesium smelting, initiating revision of industry pollution emission standards as soon as possible, and strengthening fugitive emissions control and solid waste disposal.
