[0002] Pyrometallurgical separation is a traditional metallurgical method primarily used to extract and refine metals from ores. This process involves using a metallurgical furnace to melt the ore and necessary additives into a liquid at high temperatures. Chemical reactions, such as redox reactions, separate the crude metals, which are then refined. Pyrometallurgical separation is one of the primary methods used in steel production and is the oldest and largest metallurgical method used in modern times. Various additives and fluxes are also used during the pyrometallurgical separation process to promote reactions and separate impurities.
[0003] A large amount of harmful smoke and dust will be generated during the pyrometallurgical separation process of precious metals. The smoke and dust contain a large amount of particulate matter and harmful gases. If the smoke and dust are discharged directly, these harmful substances will seriously pollute the atmospheric environment and cause a decline in air quality. In addition, the fine particles in the smoke and dust can penetrate the lungs and enter the blood, causing serious impacts on human health and may cause respiratory diseases, cardiovascular diseases and other health problems. To address the above problems, some existing devices will use smoke filtration methods to treat the smoke and dust, but the dust generated by the filtration cannot be effectively collected and cleaned, which will cause excessive dust accumulation to clog the filter plate and affect the filtering effect of the smoke and dust.
