Flash Smelting Process - an overview | ScienceDirect Topics

2.4.3.6.1 Flash Smelting Process. The flash smelting process is important in the production of nonferrous metals from sulfide minerals. 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 turbulent gas jet.
