Meaning and Definition
A pyrometallurgical process for smelting sulfide ores, especially copper and nickel, where fine, dried concentrate is injected into a hot reaction shaft where it oxidizes and melts almost instantaneously.
An industrial metallurgical technique characterized by rapid, energy-efficient smelting in a single vessel, combining roasting and smelting stages. It is a dominant modern method in non-ferrous metal production.
Dialectal Variation

- Capitalising it incorrectly when not referring to a trademark (e.g., 'Flash Smelting' vs 'flash smelting').
FAQ
Frequently Asked Questions
No, it is almost exclusively used for non-ferrous metals, particularly copper and nickel sulfides. Iron is typically produced via the blast furnace or direct reduction processes.
Its main advantages are high energy efficiency, as the oxidation of sulfides provides most of the required heat, and excellent environmental control of sulfur dioxide emissions.
The process was developed in Finland by Outokumpu (now part of Metso Outotec) in the 1940s-50s, with the first industrial-scale unit starting in 1949.
No, it is not standard usage. The term functions as a compound noun. The typical verbal construction is 'to process ore using flash smelting' or 'to smelt ore in a flash furnace'.
