In the process of smelting antimony ore in the antimony rotary furnace, environmental protection is of vital importance, and a series of effective measures need to be taken to reduce the negative impact on the environment.

Flue gas treatment is one of the key links. A large amount of flue gas will be generated during the smelting of antimony rotary furnace, which contains harmful substances such as antimony trioxide and dust. In order to reduce air pollution, an efficient dust collection system is required. The system can accurately capture antimony trioxide and dust in the flue gas and recycle them for reuse. This not only reduces the emission of harmful substances into the atmosphere and protects air quality, but also realizes the effective recovery of resources and improves resource utilization.

For the SO₂ flue gas generated by oxidative roasting, the antimony rotary furnace smelting process also makes reasonable use of it. These SO₂ flue gases are not directly discharged, but collected for acid production. Through a specific process flow, SO₂ is converted into sulfuric acid, which realizes the optimal utilization of resources, avoids SO₂ pollution to the atmosphere, and creates additional economic value.

Wastewater treatment should not be ignored either. A certain amount of wastewater will be generated during the smelting process of antimony rotary furnace, which may contain pollutants such as heavy metals. To ensure that the discharge meets the standards, the wastewater must be professionally treated. After a series of physical, chemical and biological treatment processes, the harmful substances in the wastewater are removed so that it can meet the national emission standards before being discharged.

In addition, solid waste treatment is also an important part of environmental protection work. Solid wastes such as slag and waste residue need to be harmlessly treated or comprehensively utilized. Harmless treatment can reduce its potential harm to soil and water sources, while comprehensive utilization can further tap the value of solid waste and realize the recycling of resources.

In short, these environmental protection measures in the process of smelting antimony ore in antimony rotary furnace are of great significance to protecting the environment and achieving sustainable development.
