Talk:Flash smelting - Wikipedia

It makes it sound like there is two furnaces. And one more thing... the article seems to imply that all copper sulfide ores are processed by flash smelting (in Outokumpu furnaces no less), with a 50/50 split between flash smelter recovery and oxide copper recovery.

Flash Smelting Process - Outotec

The Outotec Flash Smelting Process 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 efficient.

Upgrade of Outotec® concentrate burner at Atlantic Copper improves smelter oxygen efficiency. Uneven process air distribution in the concentrate burner has a negative impact on smelter performance, as was recently seen in the Huelva flash smelting furnace in Spain.

Flash Smelting - an overview | ScienceDirect Topics

A newer manifestation of continuous smelting–converting is flash smelting–flash converting. This process uses a (smelting) flash furnace for making molten matte and a second (converting) flash furnace for making molten copper. The matte from the smelting furnace is granulated in massive water flows, ground, and then fed to the converting ...

Flash smelting — Wikipedia Republished // WIKI 2

While the INCO flash furnace at Sudbury was the first commercial use of oxygen flash smelting, fewer smelters use the INCO flash furnace than the Outokumpu flash furnace. Flash smelting with oxygen-enriched air (the 'reaction gas') makes use of the energy contained in the concentrate to supply most of the energy required by the furnaces.

12.3 Primary Copper Smelting

Flash furnace smelting combines the operations of roasting and smelting to produce a high-grade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F).

Flash Furnace - Outotec

The furnace is often water cooled through copper cooling elements tailored for the application and lined with refractories for maximized campaign times. Since flash converting and direct-to-blister furnaces convert the feed material into blister copper by using a highly oxidative smelting reaction, the flash furnace includes bottom air cooling ...

Flash smelting - Wikipedia

The concentrate must be dried before it is injected into the furnaces and, in the case of the Outokumpu process, some of the furnaces use an optional heater to warm the reaction gas typically to 100–450 °C. The reactions in the flash smelting furnaces produce copper matte, iron oxides and sulfur dioxide.

Copper Smelting Furnace

The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England. The first patent, of any importance, for improvements in reverberatory furnaces ...
