Flash Smelting Process - an overview | ScienceDirect Topics

The flash smelting process is important in the production of non-ferrous metals from sulfide minerals. A schematic diagram of this process is given in Fig. 7.17. In this process, fine, dried mineral particles and fluxes are injected into the furnace with industrial oxygen or oxygen-enriched air. The sulfide particles are ignited and burn in the ...

Process control in flash smelting is based on mass and energy balance from which the operational parameters (oxygen coefficient, oxygen enrichment, and flux demand) are obtained to achieve matte and slag with defined compositions and at defined temperatures. Mineral compositions of copper concentrates, and their blends, have been used in order to optimize the heat process balance.
