As an intermediate link in the copper industry chain, smelting plays a connecting role. How to use copper refining furnaces to obtain refined copper that can be directly used for processing is crucial. Fire copper smelting is the main method of producing copper today, accounting for 80% to 90% of copper production.Mainly processing sulfide ore. Hydrosmelting accounts for 10% to 20% of copper production and is mainly used to process low-grade copper ores, oxidized copper ores and some complex copper ores.
Difference requirements | pyrometallurgy | hydrometallurgy |
Ore processing | Copper concentrate, various ores | Low-quality ore, fewer ore types |
Equipment | complex | simple |
Process flow Complex | high energy consumption Simple, | low energy consumption |
cost | high | low |
Environmental pollution | large amounts of sulfur dioxide emissions, air pollution, | solvent underground pollution |
Smelting quality | high quality copper, | no impurities, magazine high |
The rotary copper refining furnace is located in the smelting workshop together with the smelting furnace and converter. It is a device for refining blister copper into anode copper. By melting copper at high temperatures, removing impurities, alloying and other processes, high-quality metal materials are produced. The rotary copper refining furnace originated in the early 20th century. After decades of development, it has gradually become a mature metal smelting equipment. The rotary refining furnace is mainly composed of four parts: the furnace body, the supporting device and the drive and control system. The main related supporting equipment includes combustion devices, combustion air systems, oxidants, reducing agents, steam, compressed air, cooling water and process piping, etc. There is a furnace mouth on the cylindrical furnace body, which is used for charging and tapping copper. The furnace mouth is equipped with a furnace lid. The furnace lid is only opened during charging and copper tapping. The melting period, oxidation period and reduction period are all covered. of.
The design and operation of copper refining furnaces need to comply with relevant safety regulations and environmental protection requirements to ensure an efficient, stable and environmentally friendly copper refining process. At the same time, the copper smelting process parameters and equipment configuration must be adjusted according to the specific ore or alloy characteristics to achieve high-quality refining results.
