Matte Layer In The Blast Furnace

Lead smelting - Wikipedia

A "matte" layer forms in this step, containing most of the copper originating from the crude lead bullion and some other impurities as metal sulfides The speiss and the matte are usually sold to copper smelters where they are refined for copper processing The lead from the blast furnace, called lead bullion, then undergoes the drossing process The bullion is agitated in kettles then cooled

Smelting - an overview | ScienceDirect Topics

The furnace is computer controlled to give a specified concentrate smelting rate while producing matte and slag of desired composition and temperature Matte/slag temperature is sensed by thermocouples embedded in the furnace walls ( MacLeod, Harlen, Cockerell, & Crisafulli, 1997 )

Electric Furnace - an overview | ScienceDirect Topics

Matte is tapped intermittently from a water-cooled taphole as needed to maintain a specified level of matte in the furnace The furnace produces much less matte than slag, that is, the production ratio of matte to slag is typically 02 As a result, the matte outflow is intermittent
