Flash smelting - Wikipedia
网页The reactions in the flash smelting furnaces produce copper matte, iron oxides and sulfur dioxide. The reacted particles fall into a bath at the bottom of the furnace, where the iron oxides react with fluxes, such as silica and limestone, to form a slag. [7]
Flash Smelting - an overview | ScienceDirect Topics
网页2012年4月23日 · Flash smelting combines roasting and melting in one furnace. Most of its heat comes from oxidizing Fe and S in the concentrate feed. It requires very little hydrocarbon fuel. It accounts for ~ 3/4 of Ni sulfide smelting [28].
网页Our proven Flash Smelting technology is the cleanest and most eficient smelting method for the production of copper and nickel from sulfide concentrates. Suitable for both new and existing smelter operations, it guarantees superior performance and output while helping producers comply with ever more stringent environmental regulations.
Flash Smelting Process - Metso
网页Metso's Outotec process for Flash Smelting is one of the world’s most commonly used processes for the production of primary copper and nickel. The process is based on our flash smelting principle, which utilizes the internal energy of the feed material for smelting, minimizing the need for external fuel and making the process very energy ...

网页闪速熔炼（flash smelting）是充分利用细磨物料巨大的活性表面，强化冶炼反应过程的熔炼方法。 将金属硫化物精矿细粉和熔剂经干燥与空气一起喷入炽热的闪速炉膛内，造成良好的传热、传质条件，使化学反应以极高的速度进行。
Flash Smelting Process - an overview | ScienceDirect Topics
网页2011年2月3日 · 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.
Flash Furnace - SpringerLink
网页2023年11月25日 · The flash furnace is characterized by high productivity, low energy consumption, and high concentration of sulfur dioxide in flue gas. The flash furnace is mainly used for the smelting of copper, nickel, and other sulfide concentrates. It is classified into Outotec type (Fig. 1) and INCO type (Fig. 2) according to the furnace shape structure.
Flash Smelting - SpringerLink
网页2023年7月4日 · Flash smelting is a method in which dry fine-grained sulfide concentrates, flux for metallurgy, and oxygen or oxygen-enriched air are injected together into the smelting furnace to make the materials to be smelted rapidly in a suspended and dispersed state.
