Development Situation of Copper Flash Smelting Process

Due to flash smelting advantages,such as technical maturity,improved supporting facilities,high reaction efficiency,low energy consumption,environmental protection etc; the application of flash smelting process rapid developed in recent 30 years. The paper summarized the history of flash smelting process development,and focus on introducing the latest situation of steam dryer; enrich oxygen blast in normal temperature; high strength smelting of flash smelting. The author thought the smelting strength improving was the develop situation,which had low investment,energy saving and other advantages. But it had a series problems such as furnace overheat,raw concentrate blocking,high copper content slag,high dust generation rate,during the process. The solving methods and latest technical progress also introduced in detailed.
