Non-submerged pure oxygen top-blowing smelting  technology

Pure oxygen top-blowing copper smelting technology is a new technology researched and developed by TOMINE based on top-blowing technology, thus having the advantages of the top-blowing technology. For this technology, water-cooled  pure oxygen  lances are  used for self-heating smelting, and fixed vertical and cylindrical metallurgical furnace is used as its reactor. This technology can be used to treat sulfide concentrate and secondary copper
